Requirements

  * PHP
      + You need PHP 5.2.0 or newer, with session support (see FAQ 1.31) , the
        Standard PHP Library (SPL) extension and JSON support.
      + To support uploading of ZIP files, you need the PHP zip extension.
      + For proper support of multibyte strings (eg. UTF-8, which is currently
        the default), you should install the mbstring and ctype extensions.
      + You need GD2 support in PHP to display inline thumbnails of JPEGs
        ("image/jpeg: inline") with their original aspect ratio
      + When using the "cookie" authentication method, the mcrypt extension is
        strongly suggested for most users and is required for 64?bit machines.
        Not using mcrypt will cause phpMyAdmin to load pages significantly
        slower.
      + To support upload progress bars, see FAQ 2.9.
      + To support BLOB streaming, see PHP and MySQL requirements in FAQ 6.25.
  * MySQL 5.0 or newer (details);
  * Web browser with cookies enabled.

Introduction

phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as a
single database. To accomplish the latter you'll need a properly set up MySQL
user who can read/write only the desired database. It's up to you to look up
the appropriate part in the MySQL manual.

Currently phpMyAdmin can:

  * browse and drop databases, tables, views, columns and indexes
  * create, copy, drop, rename and alter databases, tables, columns and indexes
  * maintenance server, databases and tables, with proposals on server
    configuration
  * execute, edit and bookmark any SQL-statement, even batch-queries
  * load text files into tables
  * create^1 and read dumps of tables
  * export^1 data to various formats: CSV, XML, PDF, ISO/IEC 26300 -
    OpenDocument Text and Spreadsheet, Word, Excel and L^AT[E]X formats
  * import data and MySQL structures from Microsoft Excel and OpenDocument
    spreadsheets, as well as XML, CSV, and SQL files
  * administer multiple servers
  * manage MySQL users and privileges
  * check referential integrity in MyISAM tables
  * using Query-by-example (QBE), create complex queries automatically
    connecting required tables
  * create PDF graphics of your Database layout
  * search globally in a database or a subset of it
  * transform stored data into any format using a set of predefined functions,
    like displaying BLOB-data as image or download-link
  * track changes on databases, tables and views
  * support InnoDB tables and foreign keys (see FAQ 3.6)
  * support mysqli, the improved MySQL extension (see FAQ 1.17)
  * communicate in 62 different languages
  * synchronize two databases residing on the same as well as remote servers
    (see FAQ 9.1)

A word about users:

Many people have difficulty understanding the concept of user management with
regards to phpMyAdmin. When a user logs in to phpMyAdmin, that username and
password are passed directly to MySQL. phpMyAdmin does no account management on
its own (other than allowing one to manipulate the MySQL user account
information); all users must be valid MySQL users.

^1) phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats) dumps and
CSV exports if you use PHP with Zlib support (--with-zlib) and/or Bzip2 support
(--with-bz2). Proper support may also need changes in php.ini.

Installation

 1. Quick Install
 2. Setup script usage
 3. phpMyAdmin configuration storage
 4. Upgrading from an older version
 5. Using authentication modes

phpMyAdmin does not apply any special security methods to the MySQL database
server. It is still the system administrator's job to grant permissions on the
MySQL databases properly. phpMyAdmin's "Privileges" page can be used for this.

Warning for Mac users:
if you are on a Mac OS version before OS X, StuffIt unstuffs with Mac formats.
So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
before uploading them to your server, as PHP seems not to like Mac-style end of
lines character ("\r").

Quick Install

 1. Choose an appropriate distribution kit from the phpmyadmin.net Downloads
    page. Some kits contain only the English messages, others contain all
    languages in UTF-8 format (this should be fine in most situations), others
    contain all languages and all character sets. We'll assume you chose a kit
    whose name looks like phpMyAdmin-x.x.x-all-languages.tar.gz.
 2. Untar or unzip the distribution (be sure to unzip the subdirectories): tar
    -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz in your webserver's document
    root. If you don't have direct access to your document root, put the files
    in a directory on your local machine, and, after step 4, transfer the
    directory on your web server using, for example, ftp.
 3. Ensure that all the scripts have the appropriate owner (if PHP is running
    in safe mode, having some scripts with an owner different from the owner of
    other scripts will be a problem). See FAQ 4.2 and FAQ 1.26 for suggestions.
 4. Now you must configure your installation. There are two methods that can be
    used. Traditionally, users have hand-edited a copy of config.inc.php, but
    now a wizard-style setup script is provided for those who prefer a
    graphical installation. Creating a config.inc.php is still a quick way to
    get started and needed for some advanced features.
      + To manually create the file, simply use your text editor to create the
        file config.inc.php (you can copy config.sample.inc.php to get minimal
        configuration file) in the main (top-level) phpMyAdmin directory (the
        one that contains index.php). phpMyAdmin first loads libraries/
        config.default.php and then overrides those values with anything found
        in config.inc.php. If the default value is okay for a particular
        setting, there is no need to include it in config.inc.php. You'll need
        a few directives to get going, a simple configuration may look like
        this:

        <?php
        $cfg['blowfish_secret'] = 'ba17c1ec07d65003';  // use here a value of your choice

        $i=0;
        $i++;
        $cfg['Servers'][$i]['auth_type']     = 'cookie';
        ?>

        Or, if you prefer to not be prompted every time you log in:

        <?php

        $i=0;
        $i++;
        $cfg['Servers'][$i]['user']          = 'root';
        $cfg['Servers'][$i]['password']      = 'cbb74bc'; // use here your password
        $cfg['Servers'][$i]['auth_type']     = 'config';
        ?>

        For a full explanation of possible configuration values, see the
        Configuration Section of this document.
      + Instead of manually editing config.inc.php, you can use the Setup
        Script. First you must manually create a folder config in the
        phpMyAdmin directory. This is a security measure. On a Linux/Unix
        system you can use the following commands:

        cd phpMyAdmin
        mkdir config                        # create directory for saving
        chmod o+rw config                   # give it world writable permissions

        And to edit an existing configuration, copy it over first:

        cp config.inc.php config/           # copy current configuration for editing
        chmod o+w config/config.inc.php     # give it world writable permissions

        On other platforms, simply create the folder and ensure that your web
        server has read and write access to it. FAQ 1.26 can help with this.

        Next, open setup/ in your browser. Note that changes are not saved to
        disk until explicitly choose Save from the Configuration area of the
        screen. Normally the script saves the new config.inc.php to the config/
        directory, but if the webserver does not have the proper permissions
        you may see the error "Cannot load or save configuration." Ensure that
        the config/ directory exists and has the proper permissions - or use
        the Download link to save the config file locally and upload (via FTP
        or some similar means) to the proper location.

        Once the file has been saved, it must be moved out of the config/
        directory and the permissions must be reset, again as a security
        measure:

        mv config/config.inc.php .         # move file to current directory
        chmod o-rw config.inc.php          # remove world read and write permissions
        rm -rf config                      # remove not needed directory

        Now the file is ready to be used. You can choose to review or edit the
        file with your favorite editor, if you prefer to set some advanced
        options which the setup script does not provide.
 5. If you are using the auth_type "config", it is suggested that you protect
    the phpMyAdmin installation directory because using config does not require
    a user to enter a password to access the phpMyAdmin installation. Use of an
    alternate authentication method is recommended, for example with HTTP?AUTH
    in a .htaccess file or switch to using auth_type cookie or http. See the
    multi?user sub?section of this FAQ for additional information, especially
    FAQ 4.4.
 6. Open the main phpMyAdmin directory in your browser. phpMyAdmin should now
    display a welcome screen and your databases, or a login dialog if using
    HTTP or cookie authentication mode.
 7. You should deny access to the ./libraries and ./setup/lib subfolders in
    your webserver configuration. For Apache you can use supplied .htaccess
    file in that folder, for other webservers, you should configure this
    yourself. Such configuration prevents from possible path exposure and cross
    side scripting vulnerabilities that might happen to be found in that code.
 8. It is generally good idea to protect public phpMyAdmin installation against
    access by robots as they usually can not do anything good there. You can do
    this using robots.txt file in root of your webserver or limit access by web
    server configuration. You can find example .htaccess file which can help
    you achieve this in contrib directory in phpMyAdmin.

phpMyAdmin configuration storage

For a whole set of new features (bookmarks, comments, SQL-history, tracking
mechanism, PDF-generation, column contents transformation, etc.) you need to
create a set of special tables. Those tables can be located in your own
database, or in a central database for a multi-user installation (this database
would then be accessed by the controluser, so no other user should have rights
to it).

Please look at your ./scripts/ directory, where you should find a file called
create_tables.sql. (If you are using a Windows server, pay special attention to
FAQ 1.23).

If you already had this infrastructure and upgraded to MySQL 4.1.2 or newer,
please use ./scripts/upgrade_tables_mysql_4_1_2+.sql and then create new tables
by importing ./scripts/create_tables.sql.

You can use your phpMyAdmin to create the tables for you. Please be aware that
you may need special (administrator) privileges to create the database and
tables, and that the script may need some tuning, depending on the database
name.

After having imported the ./scripts/create_tables.sql file, you should specify
the table names in your ./config.inc.php file. The directives used for that can
be found in the Configuration section. You will also need to have a controluser
with the proper rights to those tables (see section Using authentication modes
below).

Upgrading from an older version

Simply copy ./config.inc.php from your previous installation into the newly
unpacked one. Configuration files from old versions may require some tweaking
as some options have been changed or removed; in particular, the definition of
$cfg['AttributeTypes'] has changed so you better remove it from your file and
just use the default one. For compatibility with PHP 6, remove a
set_magic_quotes_runtime(0); statement that you might find near the end of your
configuration file.

You should not copy libraries/config.default.php over config.inc.php because
the default configuration file is version-specific.

If you have upgraded your MySQL server from a version previous to 4.1.2 to
version 5.x or newer and if you use the phpMyAdmin configuration storage, you
should run the SQL script found in scripts/upgrade_tables_mysql_4_1_2+.sql.

Using authentication modes

  * HTTP and cookie authentication modes are recommended in a multi-user
    environment where you want to give users access to their own database and
    don't want them to play around with others.
    Nevertheless be aware that MS Internet Explorer seems to be really buggy
    about cookies, at least till version 6.
    Even in a single-user environment, you might prefer to use HTTP or cookie
    mode so that your user/password pair are not in clear in the configuration
    file.
  * HTTP and cookie authentication modes are more secure: the MySQL login
    information does not need to be set in the phpMyAdmin configuration file
    (except possibly for the controluser).
    However, keep in mind that the password travels in plain text, unless you
    are using the HTTPS protocol.
    In cookie mode, the password is stored, encrypted with the blowfish
    algorithm, in a temporary cookie.
  * Note: this section is only applicable if your MySQL server is running with
    --skip-show-database.

    For 'HTTP' and 'cookie' modes, phpMyAdmin needs a controluser that has only
    the SELECT privilege on the `mysql`.`user` (all columns except `Password`),
    `mysql`.`db` (all columns), `mysql`.`host` (all columns) and `mysql`.
    `tables_priv` (all columns except `Grantor` and `Timestamp`) tables.
    You must specify the details for the controluser in the config.inc.php file
    under the $cfg['Servers'][$i]['controluser'] and $cfg['Servers'][$i]
    ['controlpass'] settings.
    The following example assumes you want to use pma as the controluser and
    pmapass as the controlpass, but this is only an example: use something else
    in your file! Input these statements from the phpMyAdmin SQL Query window
    or mysql command?line client.
    Of course you have to replace localhost with the webserver's host if it's
    not the same as the MySQL server's one.

    GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
    GRANT SELECT (
        Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
        Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
        File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
        Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
        Execute_priv, Repl_slave_priv, Repl_client_priv
        ) ON mysql.user TO 'pma'@'localhost';
    GRANT SELECT ON mysql.db TO 'pma'@'localhost';
    GRANT SELECT ON mysql.host TO 'pma'@'localhost';
    GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
        ON mysql.tables_priv TO 'pma'@'localhost';

    If you want to use the many new relation and bookmark features:

    GRANT SELECT, INSERT, UPDATE, DELETE ON <pma_db>.* TO 'pma'@'localhost';

    (this of course requires that your phpMyAdmin configuration storage be set
    up).
  * Then each of the true users should be granted a set of privileges on a set
    of particular databases. Normally you shouldn't give global privileges to
    an ordinary user, unless you understand the impact of those privileges (for
    example, you are creating a superuser).
    For example, to grant the user real_user with all privileges on the
    database user_base:

    GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost IDENTIFIED BY 'real_password';

    What the user may now do is controlled entirely by the MySQL user
    management system.
    With HTTP or cookie authentication mode, you don't need to fill the user/
    password fields inside the $cfg['Servers'] array.

'HTTP' authentication mode

  * Uses HTTP Basic authentication method and allows you to log in as any valid
    MySQL user.
  * Is supported with most PHP configurations. For IIS (ISAPI) support using
    CGI PHP see FAQ 1.32, for using with Apache CGI see FAQ 1.35.
  * See also FAQ 4.4 about not using the .htaccess mechanism along with 'HTTP'
    authentication mode.

'cookie' authentication mode

  * You can use this method as a replacement for the HTTP authentication (for
    example, if you're running IIS).
  * Obviously, the user must enable cookies in the browser, but this is now a
    requirement for all authentication modes.
  * With this mode, the user can truly log out of phpMyAdmin and log in back
    with the same username.
  * If you want to log in to arbitrary server see $cfg['AllowArbitraryServer']
    directive.
  * As mentioned in the requirements section, having the mcrypt extension will
    speed up access considerably, but is not required.

'signon' authentication mode

  * This mode is a convenient way of using credentials from another application
    to authenticate to phpMyAdmin.
  * The other application has to store login information into session data.
  * More details in the auth_type section.

'config' authentication mode

  * This mode is the less secure one because it requires you to fill the $cfg
    ['Servers'][$i]['user'] and $cfg['Servers'][$i]['password'] fields (and as
    a result, anyone who can read your config.inc.php can discover your
    username and password).
    But you don't need to setup a "controluser" here: using the $cfg['Servers']
    [$i]['only_db'] might be enough.
  * In the ISP FAQ section, there is an entry explaining how to protect your
    configuration file.
  * For additional security in this mode, you may wish to consider the Host
    authentication $cfg['Servers'][$i]['AllowDeny']['order'] and $cfg
    ['Servers'][$i]['AllowDeny']['rules'] configuration directives.
  * Unlike cookie and http, does not require a user to log in when first
    loading the phpMyAdmin site. This is by design but could allow any user to
    access your installation. Use of some restriction method is suggested,
    perhaps a .htaccess file with the HTTP-AUTH directive or disallowing
    incoming HTTP requests at one?s router or firewall will suffice (both of
    which are beyond the scope of this manual but easily searchable with
    Google).

Swekey authentication

The Swekey is a low cost authentication USB key that can be used in web
applications.

When Swekey authentication is activated, phpMyAdmin requires the users's Swekey
to be plugged before entering the login page (currently supported for cookie
authentication mode only). Swekey Authentication is disabled by default.

To enable it, add the following line to config.inc.php:

$cfg['Servers'][$i]['auth_swekey_config'] = '/etc/swekey.conf';

You then have to create the swekey.conf file that will associate each user with
their Swekey Id. It is important to place this file outside of your web
server's document root (in the example, it is located in /etc). A self
documented sample file is provided in the contrib directory. Feel free to use
it with your own users' information.

If you want to purchase a Swekey please visit http://phpmyadmin.net/auth_key
since this link provides funding for phpMyAdmin.

Configuration

Warning for Mac users: PHP does not seem to like Mac end of lines character ("\
r"). So ensure you choose the option that allows to use the *nix end of line
character ("\n") in your text editor before saving a script you have modified.

Configuration note: Almost all configurable data is placed in config.inc.php.
If this file does not exist, please refer to the Quick install section to
create one. This file only needs to contain the parameters you want to change
from their corresponding default value in libraries/config.default.php.

The parameters which relate to design (like colors) are placed in themes/
themename/layout.inc.php. You might also want to create config.footer.inc.php
and config.header.inc.php files to add your site specific code to be included
on start and end of each page.

$cfg['PmaAbsoluteUri'] string
    Sets here the complete URL (with full path) to your phpMyAdmin
    installation's directory. E.g. http://www.your_web.net/
    path_to_your_phpMyAdmin_directory/. Note also that the URL on some web
    servers are case?sensitive. Don?t forget the trailing slash at the end.

    Starting with version 2.3.0, it is advisable to try leaving this blank. In
    most cases phpMyAdmin automatically detects the proper setting. Users of
    port forwarding will need to set PmaAbsoluteUri (more info). A good test is
    to browse a table, edit a row and save it. There should be an error message
    if phpMyAdmin is having trouble auto?detecting the correct value. If you
    get an error that this must be set or if the autodetect code fails to
    detect your path, please post a bug report on our bug tracker so we can
    improve the code.
$cfg['PmaNoRelation_DisableWarning'] boolean
    Starting with version 2.3.0 phpMyAdmin offers a lot of features to work
    with master / foreign ? tables (see $cfg['Servers'][$i]['pmadb']).
    If you tried to set this up and it does not work for you, have a look on
    the "Structure" page of one database where you would like to use it. You
    will find a link that will analyze why those features have been disabled.
    If you do not want to use those features set this variable to TRUE to stop
    this message from appearing.
$cfg['SuhosinDisableWarning'] boolean
    A warning is displayed on the main page if Suhosin is detected. You can set
    this parameter to TRUE to stop this message from appearing.
$cfg['McryptDisableWarning'] boolean
    Disable the default warning that is displayed if mcrypt is missing for
    cookie authentication. You can set this parameter to TRUE to stop this
    message from appearing.
$cfg['TranslationWarningThreshold'] integer
    Show warning about incomplete translations on certain threshold.
$cfg['AllowThirdPartyFraming'] boolean
    Setting this to true allows a page located on a different domain to call
    phpMyAdmin inside a frame, and is a potential security hole allowing
    cross-frame scripting attacks.
$cfg['blowfish_secret'] string
    The "cookie" auth_type uses blowfish algorithm to encrypt the password.
    If you are using the "cookie" auth_type, enter here a random passphrase of
    your choice. It will be used internally by the blowfish algorithm: you
    won?t be prompted for this passphrase. There is no maximum length for this
    secret.

    Since version 3.1.0 phpMyAdmin can generate this on the fly, but it makes a
    bit weaker security as this generated secret is stored in session and
    furthermore it makes impossible to recall user name from cookie.
$cfg['Servers'] array
    Since version 1.4.2, phpMyAdmin supports the administration of multiple
    MySQL servers. Therefore, a $cfg['Servers']-array has been added which
    contains the login information for the different servers. The first $cfg
    ['Servers'][$i]['host'] contains the hostname of the first server, the
    second $cfg['Servers'][$i]['host'] the hostname of the second server, etc.
    In ./libraries/config.default.php, there is only one section for server
    definition, however you can put as many as you need in ./config.inc.php,
    copy that block or needed parts (you don't have to define all settings,
    just those you need to change).
$cfg['Servers'][$i]['host'] string
    The hostname or IP address of your $i-th MySQL-server. E.g. localhost.
$cfg['Servers'][$i]['port'] string
    The port-number of your $i-th MySQL-server. Default is 3306 (leave blank).
    If you use "localhost" as the hostname, MySQL ignores this port number and
    connects with the socket, so if you want to connect to a port different
    from the default port, use "127.0.0.1" or the real hostname in $cfg
    ['Servers'][$i]['host'].
$cfg['Servers'][$i]['socket'] string
    The path to the socket to use. Leave blank for default.
    To determine the correct socket, check your MySQL configuration or, using
    the mysql command?line client, issue the status command. Among the
    resulting information displayed will be the socket used.
$cfg['Servers'][$i]['ssl'] boolean
    Whether to enable SSL for connection to MySQL server.
$cfg['Servers'][$i]['connect_type'] string
    What type connection to use with the MySQL server. Your options are
    'socket' and 'tcp'. It defaults to 'tcp' as that is nearly guaranteed to be
    available on all MySQL servers, while sockets are not supported on some
    platforms.

    To use the socket mode, your MySQL server must be on the same machine as
    the Web server.
$cfg['Servers'][$i]['extension'] string
    What php MySQL extension to use for the connection. Valid options are:

    mysql : The classic MySQL extension. This is the recommended and default
    method at this time.

    mysqli : The improved MySQL extension. This extension became available with
    php 5.0.0 and is the recommended way to connect to a server running MySQL
    4.1.x or newer.
$cfg['Servers'][$i]['compress'] boolean
    Whether to use a compressed protocol for the MySQL server connection or not
    (experimental).
    This feature requires PHP >= 4.3.0.
$cfg['Servers'][$i]['controluser'] string
    $cfg['Servers'][$i]['controlpass'] string
    This special account is used for 2 distinct purposes: to make possible all
    relational features (see $cfg['Servers'][$i]['pmadb']) and, for a MySQL
    server running with --skip-show-database, to enable a multi-user
    installation (HTTP or cookie authentication mode).

    When using HTTP or cookie authentication modes (or 'config' authentication
    mode since phpMyAdmin 2.2.1), you need to supply the details of a MySQL
    account that has SELECT privilege on the mysql.user (all columns except
    "Password"), mysql.db (all columns) and mysql.tables_priv (all columns
    except "Grantor" and "Timestamp") tables. This account is used to check
    what databases the user will see at login.
    Please see the install section on "Using authentication modes" for more
    information.

    In phpMyAdmin versions before 2.2.5, those were called "stduser/stdpass".
$cfg['Servers'][$i]['auth_type'] string ['HTTP'|'http'|'cookie'|'config'|
    'signon']
    Whether config or cookie or HTTP or signon authentication should be used
    for this server.
      + 'config' authentication ($auth_type = 'config') is the plain old way:
        username and password are stored in config.inc.php.
      + 'cookie' authentication mode ($auth_type = 'cookie') as introduced in
        2.2.3 allows you to log in as any valid MySQL user with the help of
        cookies. Username and password are stored in cookies during the session
        and password is deleted when it ends. This can also allow you to log in
        in arbitrary server if $cfg['AllowArbitraryServer'] enabled.
      + 'HTTP' authentication (was called 'advanced' in previous versions and
        can be written also as 'http') ($auth_type = 'HTTP') as introduced in
        1.3.0 allows you to log in as any valid MySQL user via HTTP-Auth.
      + 'signon' authentication mode ($auth_type = 'signon') as introduced in
        2.10.0 allows you to log in from prepared PHP session data. This is
        useful for implementing single signon from another application. Sample
        way how to seed session is in signon example: scripts/signon.php. There
        is also alternative example using OpenID - scripts/openid.php. You need
        to configure session name and signon URL to use this authentication
        method.
    Please see the install section on "Using authentication modes" for more
    information.
$cfg['Servers'][$i]['auth_http_realm'] string
    When using auth_type = 'HTTP', this field allows to define a custom HTTP
    Basic Auth Realm which will be displayed to the user. If not explicitly
    specified in your configuration, a string combined of "phpMyAdmin " and
    either $cfg['Servers'][$i]['verbose'] or $cfg['Servers'][$i]['host'] will
    be used.
$cfg['Servers'][$i]['auth_swekey_config'] string
    The name of the file containing Swekey ids and login names for hardware
    authentication. Leave empty to deactivate this feature.
$cfg['Servers'][$i]['user'] string
    $cfg['Servers'][$i]['password'] string
    When using auth_type = 'config', this is the user/password-pair which
    phpMyAdmin will use to connect to the MySQL server. This user/password pair
    is not needed when HTTP or cookie authentication is used and should be
    empty.
$cfg['Servers'][$i]['nopassword'] boolean
    Allow attempt to log in without password when a login with password fails.
    This can be used together with http authentication, when authentication is
    done some other way and phpMyAdmin gets user name from auth and uses empty
    password for connecting to MySQL. Password login is still tried first, but
    as fallback, no password method is tried.
$cfg['Servers'][$i]['only_db'] string or array
    If set to a (an array of) database name(s), only this (these) database(s)
    will be shown to the user. Since phpMyAdmin 2.2.1, this/these database(s)
    name(s) may contain MySQL wildcards characters ("_" and "%"): if you want
    to use literal instances of these characters, escape them (I.E. use 'my\
    _db' and not 'my_db').
    This setting is an efficient way to lower the server load since the latter
    does not need to send MySQL requests to build the available database list.
    But it does not replace the privileges rules of the MySQL database server.
    If set, it just means only these databases will be displayed but not that
    all other databases can't be used.

    An example of using more that one database: $cfg['Servers'][$i]['only_db']
    = array('db1', 'db2');

    As of phpMyAdmin 2.5.5 the order inside the array is used for sorting the
    databases in the left frame, so that you can individually arrange your
    databases.
    If you want to have certain databases at the top, but don't care about the
    others, you do not need to specify all other databases. Use: $cfg
    ['Servers'][$i]['only_db'] = array('db3', 'db4', '*'); instead to tell
    phpMyAdmin that it should display db3 and db4 on top, and the rest in
    alphabetic order.
$cfg['Servers'][$i]['hide_db'] string
    Regular expression for hiding some databases from unprivileged users. This
    only hides them from listing, but a user is still able to access them
    (using, for example, the SQL query area). To limit access, use the MySQL
    privilege system.

    For example, to hide all databases starting with the letter "a", use

    $cfg['Servers'][$i]['hide_db'] = '^a';

    and to hide both "db1" and "db2" use

    $cfg['Servers'][$i]['hide_db'] = '^(db1|db2)$';

    More information on regular expressions can be found in the PCRE pattern
    syntax portion of the PHP reference manual.
$cfg['Servers'][$i]['verbose'] string
    Only useful when using phpMyAdmin with multiple server entries. If set,
    this string will be displayed instead of the hostname in the pull-down menu
    on the main page. This can be useful if you want to show only certain
    databases on your system, for example. For HTTP auth, all non-US-ASCII
    characters will be stripped.
$cfg['Servers'][$i]['pmadb'] string
    The name of the database containing the phpMyAdmin configuration storage.

    See the phpMyAdmin configuration storage section in this document to see
    the benefits of this feature, and for a quick way of creating this database
    and the needed tables.

    If you are the only user of this phpMyAdmin installation, you can use your
    current database to store those special tables; in this case, just put your
    current database name in $cfg['Servers'][$i]['pmadb']. For a multi-user
    installation, set this parameter to the name of your central database
    containing the phpMyAdmin configuration storage.
$cfg['Servers'][$i]['bookmarktable'] string
    Since release 2.2.0 phpMyAdmin allows users to bookmark queries. This can
    be useful for queries you often run.

    To allow the usage of this functionality:
      + set up pmadb and the phpMyAdmin configuration storage
      + enter the table name in $cfg['Servers'][$i]['bookmarktable']
$cfg['Servers'][$i]['relation'] string
    Since release 2.2.4 you can describe, in a special 'relation' table, which
    column is a key in another table (a foreign key). phpMyAdmin currently uses
    this to
      + make clickable, when you browse the master table, the data values that
        point to the foreign table;
      + display in an optional tool-tip the "display column" when browsing the
        master table, if you move the mouse to a column containing a foreign
        key (use also the 'table_info' table);
        (see FAQ 6.7)
      + in edit/insert mode, display a drop-down list of possible foreign keys
        (key value and "display column" are shown)
        (see FAQ 6.21)
      + display links on the table properties page, to check referential
        integrity (display missing foreign keys) for each described key;
      + in query-by-example, create automatic joins (see FAQ 6.6)
      + enable you to get a PDF schema of your database (also uses the
        table_coords table).
    The keys can be numeric or character.

    To allow the usage of this functionality:
      + set up pmadb and the phpMyAdmin configuration storage
      + put the relation table name in $cfg['Servers'][$i]['relation']
      + now as normal user open phpMyAdmin and for each one of your tables
        where you want to use this feature, click "Structure/Relation view/"
        and choose foreign columns.
    Please note that in the current version, master_db must be the same as
    foreign_db. Those columns have been put in future development of the
    cross-db relations.
$cfg['Servers'][$i]['table_info'] string
    Since release 2.3.0 you can describe, in a special 'table_info' table,
    which column is to be displayed as a tool-tip when moving the cursor over
    the corresponding key.
    This configuration variable will hold the name of this special table. To
    allow the usage of this functionality:
      + set up pmadb and the phpMyAdmin configuration storage
      + put the table name in $cfg['Servers'][$i]['table_info'] (e.g.
        'pma_table_info')
      + then for each table where you want to use this feature, click
        "Structure/Relation view/Choose column to display" to choose the
        column.
    Usage tip: Display column.
$cfg['Servers'][$i]['table_coords'] string
    $cfg['Servers'][$i]['pdf_pages'] string
    Since release 2.3.0 you can have phpMyAdmin create PDF pages showing the
    relations between your tables. To do this it needs two tables "pdf_pages"
    (storing information about the available PDF pages) and "table_coords"
    (storing coordinates where each table will be placed on a PDF schema
    output).

    You must be using the "relation" feature.

    To allow the usage of this functionality:
      + set up pmadb and the phpMyAdmin configuration storage
      + put the correct table names in $cfg['Servers'][$i]['table_coords'] and
        $cfg['Servers'][$i]['pdf_pages']
    Usage tips: PDF output.
$cfg['Servers'][$i]['column_info'] string
    Since release 2.3.0 you can store comments to describe each column for each
    table. These will then be shown on the "printview".

    Starting with release 2.5.0, comments are consequently used on the table
    property pages and table browse view, showing up as tool-tips above the
    column name (properties page) or embedded within the header of table in
    browse view. They can also be shown in a table dump. Please see the
    relevant configuration directives later on.

    Also new in release 2.5.0 is a MIME-transformation system which is also
    based on the following table structure. See Transformations for further
    information. To use the MIME-transformation system, your column_info table
    has to have the three new columns 'mimetype', 'transformation',
    'transformation_options'.

    To allow the usage of this functionality:
      + set up pmadb and the phpMyAdmin configuration storage
      + put the table name in $cfg['Servers'][$i]['column_info'] (e.g.
        'pma_column_info')
      + to update your PRE-2.5.0 Column_comments Table use this:

        ALTER TABLE `pma_column_comments`
            ADD `mimetype` VARCHAR( 255 ) NOT NULL,
            ADD `transformation` VARCHAR( 255 ) NOT NULL,
            ADD `transformation_options` VARCHAR( 255 ) NOT NULL;

        and remember that the Variable in config.inc.php has been renamed from
        $cfg['Servers'][$i]['column_comments'] to $cfg['Servers'][$i]
        ['column_info']
$cfg['Servers'][$i]['history'] string
    Since release 2.5.0 you can store your SQL history, which means all queries
    you entered manually into the phpMyAdmin interface. If you don't want to
    use a table-based history, you can use the JavaScript-based history. Using
    that, all your history items are deleted when closing the window.

    Using $cfg['QueryHistoryMax'] you can specify an amount of history items
    you want to have on hold. On every login, this list gets cut to the maximum
    amount.

    The query history is only available if JavaScript is enabled in your
    browser.

    To allow the usage of this functionality:
      + set up pmadb and the phpMyAdmin configuration storage
      + put the table name in $cfg['Servers'][$i]['history'] (e.g.
        'pma_history')
$cfg['Servers'][$i]['tracking'] string
    Since release 3.3.x a tracking mechanism is available. It helps you to
    track every SQL command which is executed by phpMyAdmin. The mechanism
    supports logging of data manipulation and data definition statements. After
    enabling it you can create versions of tables.

    The creation of a version has two effects:
      + phpMyAdmin saves a snapshot of the table, including structure and
        indexes.
      + phpMyAdmin logs all commands which change the structure and/or data of
        the table and links these commands with the version number.
    Of course you can view the tracked changes. On the "Tracking" page a
    complete report is available for every version. For the report you can use
    filters, for example you can get a list of statements within a date range.
    When you want to filter usernames you can enter * for all names or you
    enter a list of names separated by ','. In addition you can export the
    (filtered) report to a file or to a temporary database.

    To allow the usage of this functionality:
      + set up pmadb and the phpMyAdmin configuration storage
      + put the table name in $cfg['Servers'][$i]['tracking'] (e.g.
        'pma_tracking')
$cfg['Servers'][$i]['tracking_version_auto_create'] boolean
    Whether the tracking mechanism creates versions for tables and views
    automatically. Default value is false.

    If this is set to true and you create a table or view with
      + CREATE TABLE ...
      + CREATE VIEW ...
    and no version exists for it, the mechanism will create a version for you
    automatically.
$cfg['Servers'][$i]['tracking_default_statements'] string
    Defines the list of statements the auto-creation uses for new versions.
    Default value is

    CREATE TABLE,ALTER TABLE,DROP TABLE,RENAME TABLE,
    CREATE INDEX,DROP INDEX,
    INSERT,UPDATE,DELETE,TRUNCATE,REPLACE,
    CREATE VIEW,ALTER VIEW,DROP VIEW,
    CREATE DATABASE,ALTER DATABASE,DROP DATABASE

$cfg['Servers'][$i]['tracking_add_drop_view'] boolean
    Whether a DROP VIEW IF EXISTS statement will be added as first line to the
    log when creating a view. Default value is true.

$cfg['Servers'][$i]['tracking_add_drop_table'] boolean
    Whether a DROP TABLE IF EXISTS statement will be added as first line to the
    log when creating a table. Default value is true.

$cfg['Servers'][$i]['tracking_add_drop_database'] boolean
    Whether a DROP DATABASE IF EXISTS statement will be added as first line to
    the log when creating a database. Default value is true.

$cfg['Servers'][$i]['userconfig'] string
    Since release 3.4.x phpMyAdmin allows users to set most preferences by
    themselves and store them in the database.

    If you don't allow for storing preferences in pmadb, users can still
    personalize phpMyAdmin, but settings will be saved in browser's local
    storage, or, it is is unavailable, until the end of session.

    To allow the usage of this functionality:
      + set up pmadb and the phpMyAdmin configuration storage
      + put the table name in $cfg['Servers'][$i]['userconfig']
$cfg['Servers'][$i]['designer_coords'] string
    Since release 2.10.0 a Designer interface is available; it permits to
    visually manage the relations.

    To allow the usage of this functionality:
      + set up pmadb and the phpMyAdmin configuration storage
      + put the table name in $cfg['Servers'][$i]['designer_coords'] (e.g.
        'pma_designer_coords')
$cfg['Servers'][$i]['verbose_check'] boolean
    Because release 2.5.0 introduced the new MIME-transformation support, the
    column_info table got enhanced with three new columns. If the above
    variable is set to TRUE (default) phpMyAdmin will check if you have the
    latest table structure available. If not, it will emit a warning to the
    superuser.

    You can disable this checking behavior by setting the variable to false,
    which should offer a performance increase.

    Recommended to set to FALSE, when you are sure, your table structure is up
    to date.
$cfg['Servers'][$i]['AllowRoot'] boolean
    Whether to allow root access. This is just a shortcut for the AllowDeny
    rules below.
$cfg['Servers'][$i]['AllowNoPassword'] boolean
    Whether to allow logins without a password. The default value of false for
    this parameter prevents unintended access to a MySQL server with was left
    with an empty password for root or on which an anonymous (blank) user is
    defined.
$cfg['Servers'][$i]['AllowDeny']['order'] string
    If your rule order is empty, then IP authorization is disabled.

    If your rule order is set to 'deny,allow' then the system applies all deny
    rules followed by allow rules. Access is allowed by default. Any client
    which does not match a Deny command or does match an Allow command will be
    allowed access to the server.

    If your rule order is set to 'allow,deny' then the system applies all allow
    rules followed by deny rules. Access is denied by default. Any client which
    does not match an Allow directive or does match a Deny directive will be
    denied access to the server.

    If your rule order is set to 'explicit', authorization is performed in a
    similar fashion to rule order 'deny,allow', with the added restriction that
    your host/username combination must be listed in the allow rules, and not
    listed in the deny rules. This is the most secure means of using Allow/Deny
    rules, and was available in Apache by specifying allow and deny rules
    without setting any order.

    Please also see $cfg['TrustedProxies'] for detecting IP address behind
    proxies.
$cfg['Servers'][$i]['AllowDeny']['rules'] array of strings
    The general format for the rules is as such:

    <'allow' | 'deny'> <username> [from] <ipmask>

    If you wish to match all users, it is possible to use a '%' as a wildcard
    in the username field.
    There are a few shortcuts you can use in the ipmask field as well (please
    note that those containing SERVER_ADDRESS might not be available on all
    webservers):

    'all' -> 0.0.0.0/0
    'localhost' -> 127.0.0.1/8
    'localnetA' -> SERVER_ADDRESS/8
    'localnetB' -> SERVER_ADDRESS/16
    'localnetC' -> SERVER_ADDRESS/24

    Having an empty rule list is equivalent to either using 'allow % from all'
    if your rule order is set to 'deny,allow' or 'deny % from all' if your rule
    order is set to 'allow,deny' or 'explicit'.

    For the IP matching system, the following work:
    xxx.xxx.xxx.xxx (an exact IP address)
    xxx.xxx.xxx.[yyy-zzz] (an IP address range)
    xxx.xxx.xxx.xxx/nn (CIDR, Classless Inter-Domain Routing type IP addresses)
    But the following does not work:
    xxx.xxx.xxx.xx[yyy-zzz] (partial IP address range)
    Also IPv6 addresses are not supported.
$cfg['Servers'][$i]['DisableIS'] boolean
    Disable using INFORMATION_SCHEMA to retrieve information (use SHOW commands
    instead), because of speed issues when many databases are present.
    Currently used in some parts of the code, more to come.
$cfg['Servers'][$i]['ShowDatabasesCommand'] string
    On a server with a huge number of databases, the default SHOW DATABASES
    command used to fetch the name of available databases will probably be too
    slow, so it can be replaced by faster commands (see libraries/
    config.default.php for examples).
$cfg['Servers'][$i]['CountTables'] boolean
    Whether to count the number of tables for each database when preparing the
    list of databases for the navigation frame.
$cfg['Servers'][$i]['SignonSession'] string
    Name of session which will be used for signon authentication method.
$cfg['Servers'][$i]['SignonURL'] string
    URL where user will be redirected to log in for signon authentication
    method. Should be absolute including protocol.
$cfg['Servers'][$i]['LogoutURL'] string
    URL where user will be redirected after logout (doesn't affect config
    authentication method). Should be absolute including protocol.
$cfg['ServerDefault'] integer
    If you have more than one server configured, you can set $cfg
    ['ServerDefault'] to any one of them to autoconnect to that server when
    phpMyAdmin is started, or set it to 0 to be given a list of servers without
    logging in.
    If you have only one server configured, $cfg['ServerDefault'] MUST be set
    to that server.
$cfg['AjaxEnable'] boolean
    Defines whether to refresh only parts of certain pages using Ajax
    techniques. Applies only where a non-Ajax behavior is possible; for
    example, the Designer feature is Ajax-only so this directive does not apply
    to it.
$cfg['VersionCheck'] boolean
    Enables check for latest versions using javascript on main phpMyAdmin page.
$cfg['MaxDbList'] integer
    The maximum number of database names to be displayed in the navigation
    frame and the database list.
$cfg['MaxTableList'] integer
    The maximum number of table names to be displayed in the main panel's list
    (except on the Export page). This limit is also enforced in the navigation
    panel when in Light mode.
$cfg['MaxCharactersInDisplayedSQL'] integer
    The maximum number of characters when a SQL query is displayed. The default
    limit of 1000 should be correct to avoid the display of tons of hexadecimal
    codes that represent BLOBs, but some users have real SQL queries that are
    longer than 1000 characters. Also, if a query's length exceeds this limit,
    this query is not saved in the history.
$cfg['OBGzip'] string/boolean
    Defines whether to use GZip output buffering for increased speed in HTTP
    transfers.
    Set to true/false for enabling/disabling. When set to 'auto' (string),
    phpMyAdmin tries to enable output buffering and will automatically disable
    it if your browser has some problems with buffering. IE6 with a certain
    patch is known to cause data corruption when having enabled buffering.
$cfg['PersistentConnections'] boolean
    Whether persistent connections should be used or not (mysql_connect or
    mysql_pconnect).
$cfg['ForceSSL'] boolean
    Whether to force using https while accessing phpMyAdmin.
$cfg['ExecTimeLimit'] integer [number of seconds]
    Set the number of seconds a script is allowed to run. If seconds is set to
    zero, no time limit is imposed.
    This setting is used while importing/exporting dump files and in the
    Synchronize feature but has no effect when PHP is running in safe mode.
$cfg['SessionSavePath'] string
    Path for storing session data (session_save_path PHP parameter).
$cfg['MemoryLimit'] string [number of bytes]
    Set the number of bytes a script is allowed to allocate. If set to zero, no
    limit is imposed.
    This setting is used while importing/exporting dump files and at some other
    places in phpMyAdmin so you definitely don't want to put here a too low
    value. It has no effect when PHP is running in safe mode.
    You can also use any string as in php.ini, eg. '16M'. Ensure you don't omit
    the suffix (16 means 16 bytes!)
$cfg['SkipLockedTables'] boolean
    Mark used tables and make it possible to show databases with locked tables
    (since MySQL 3.23.30).
$cfg['ShowSQL'] boolean
    Defines whether SQL queries generated by phpMyAdmin should be displayed or
    not.
$cfg['AllowUserDropDatabase'] boolean
    Defines whether normal users (non-administrator) are allowed to delete
    their own database or not. If set as FALSE, the link "Drop Database" will
    not be shown, and even a "DROP DATABASE mydatabase" will be rejected. Quite
    practical for ISP's with many customers.
    Please note that this limitation of SQL queries is not as strict as when
    using MySQL privileges. This is due to nature of SQL queries which might be
    quite complicated. So this choice should be viewed as help to avoid
    accidental dropping rather than strict privilege limitation.
$cfg['Confirm'] boolean
    Whether a warning ("Are your really sure...") should be displayed when
    you're about to lose data.
$cfg['LoginCookieRecall'] boolean
    Define whether the previous login should be recalled or not in cookie
    authentication mode.

    This is automatically disabled if you do not have configured $cfg
    ['blowfish_secret'].
$cfg['LoginCookieValidity'] integer [number of seconds]
    Define how long is login cookie valid. Please note that php configuration
    option session.gc_maxlifetime might limit session validity and if session
    is lost, login cookie is also invalidated. So it is a good idea to set
    session.gc_maxlifetime not lower than the value of $cfg
    ['LoginCookieValidity'].
$cfg['LoginCookieStore'] integer [number of seconds]
    Define how long login cookie should be stored in browser. Default 0 means
    that it will be kept for existing session. This is recommended for not
    trusted environments.
$cfg['LoginCookieDeleteAll'] boolean
    If enabled (default), logout deletes cookies for all servers, otherwise
    only for current one. Setting this to false makes it easy to forget to log
    out from other server, when you are using more of them.
$cfg['UseDbSearch'] boolean
    Define whether the "search string inside database" is enabled or not.
$cfg['IgnoreMultiSubmitErrors'] boolean
    Define whether phpMyAdmin will continue executing a multi-query statement
    if one of the queries fails. Default is to abort execution.
$cfg['VerboseMultiSubmit'] boolean
    Define whether phpMyAdmin will output the results of each query of a
    multi-query statement embedded into the SQL output as inline comments.
    Defaults to TRUE.
$cfg['AllowArbitraryServer'] boolean
    If enabled, allows you to log in to arbitrary servers using cookie auth and
    permits to specify servers of your choice in the Synchronize dialog.

    NOTE: Please use this carefully, as this may allow users access to MySQL
    servers behind the firewall where your HTTP server is placed.
$cfg['Error_Handler']['display'] boolean
    Whether to display errors from PHP or not.
$cfg['Error_Handler']['gather'] boolean
    Whether to gather errors from PHP or not.
$cfg['LeftFrameLight'] boolean
    Defines whether to use a select-based menu and display only the current
    tables in the left frame (smaller page). Only in Non-Lightmode you can use
    the feature to display nested folders using $cfg['LeftFrameTableSeparator']
$cfg['LeftFrameDBTree'] boolean
    In light mode, defines whether to display the names of databases (in the
    selector) using a tree, see also $cfg['LeftFrameDBSeparator'].
$cfg['LeftFrameDBSeparator'] string or array
    The string used to separate the parts of the database name when showing
    them in a tree. Alternatively you can specify more strings in an array and
    all of them will be used as a separator.
$cfg['LeftFrameTableSeparator'] string
    Defines a string to be used to nest table spaces. Defaults to '__'. This
    means if you have tables like 'first__second__third' this will be shown as
    a three-level hierarchy like: first > second > third. If set to FALSE or
    empty, the feature is disabled. NOTE: You should not use this separator at
    the beginning or end of a table name or multiple times after another
    without any other characters in between.
$cfg['LeftFrameTableLevel'] string
    Defines how many sublevels should be displayed when splitting up tables by
    the above separator.
$cfg['ShowTooltip'] boolean
    Defines whether to display table comment as tool-tip in left frame or not.
$cfg['ShowTooltipAliasDB'] boolean
    If tool-tips are enabled and a DB comment is set, this will flip the
    comment and the real name. That means that if you have a table called
    'user0001' and add the comment 'MyName' on it, you will see the name
    'MyName' used consequently in the left frame and the tool-tip shows the
    real name of the DB.
$cfg['ShowTooltipAliasTB'] boolean/string
    Same as $cfg['ShowTooltipAliasDB'], except this works for table names. When
    setting this to 'nested', the Alias of the Tablename is only used to split/
    nest the tables according to the $cfg['LeftFrameTableSeparator'] directive.
    So only the folder is called like the Alias, the tablename itself stays the
    real tablename.
$cfg['LeftDisplayLogo'] boolean
    Defines whether or not to display the phpMyAdmin logo at the top of the
    left frame. Defaults to TRUE.
$cfg['LeftLogoLink'] string
    Enter URL where logo in the navigation frame will point to. For use
    especially with self made theme which changes this. The default value for
    this is main.php.
$cfg['LeftLogoLinkWindow'] string
    Whether to open the linked page in the main window (main) or in a new one
    (new). Note: use new if you are linking to phpmyadmin.net.
$cfg['LeftDisplayTableFilterMinimum'] integer
    Defines the minimum number of tables to display a JavaScript filter box
    above the list of tables in the left frame. Defaults to 30. To disable the
    filter completely some high number can he used (e.g. 9999)
$cfg['LeftDisplayServers'] boolean
    Defines whether or not to display a server choice at the top of the left
    frame. Defaults to FALSE.
$cfg['DisplayServersList'] boolean
    Defines whether to display this server choice as links instead of in a
    drop-down. Defaults to FALSE (drop-down).
$cfg['DisplayDatabasesList'] boolean or text
    Defines whether to display database choice in light navigation frame as
    links instead of in a drop-down. Defaults to 'auto' - on main page list is
    shown, when database is selected, only drop down is displayed.
$cfg['LeftDefaultTabTable'] string
    Defines the tab displayed by default when clicking the small icon next to
    each table name in the navigation panel. Possible values:
    "tbl_structure.php", "tbl_sql.php", "tbl_select.php", "tbl_change.php" or
    "sql.php".
$cfg['ShowStats'] boolean
    Defines whether or not to display space usage and statistics about
    databases and tables.
    Note that statistics requires at least MySQL 3.23.3 and that, at this date,
    MySQL doesn't return such information for Berkeley DB tables.
$cfg['ShowServerInfo'] boolean
    Defines whether to display detailed server information on main page. You
    can additionally hide more information by using $cfg['Servers'][$i]
    ['verbose'].
$cfg['ShowPhpInfo'] boolean
    $cfg['ShowChgPassword'] boolean
    $cfg['ShowCreateDb'] boolean
    Defines whether to display the "PHP information" and "Change password "
    links and form for creating database or not at the starting main (right)
    frame. This setting does not check MySQL commands entered directly.

    Please note that to block the usage of phpinfo() in scripts, you have to
    put this in your php.ini:

    disable_functions = phpinfo()

    Also note that enabling the "Change password " link has no effect with
    "config" authentication mode: because of the hard coded password value in
    the configuration file, end users can't be allowed to change their
    passwords.
$cfg['SuggestDBName'] boolean
    Defines whether to suggest a database name on the "Create Database" form or
    to keep the textfield empty.
$cfg['NavigationBarIconic'] string
    Defines whether navigation bar buttons and the right panel top menu contain
    text or symbols only. A value of TRUE displays icons, FALSE displays text
    and 'both' displays both icons and text.
$cfg['ShowAll'] boolean
    Defines whether a user should be displayed a "show all (records)" button in
    browse mode or not.
$cfg['MaxRows'] integer
    Number of rows displayed when browsing a result set. If the result set
    contains more rows, "Previous" and "Next" links will be shown.
$cfg['Order'] string [DESC|ASC|SMART]
    Defines whether columns are displayed in ascending (ASC) order, in
    descending (DESC) order or in a "smart" (SMART) order - I.E. descending
    order for columns of type TIME, DATE, DATETIME and TIMESTAMP, ascending
    order else- by default.
$cfg['DisplayBinaryAsHex'] boolean
    Defines whether the "Show binary contents as HEX" browse option is ticked
    by default.
$cfg['ProtectBinary'] boolean or string
    Defines whether BLOB or BINARY columns are protected from editing when
    browsing a table's content. Valid values are:
      + FALSE to allow editing of all columns;
      + 'blob' to allow editing of all columns except BLOBS;
      + 'all' to disallow editing of all BINARY or BLOB columns.
$cfg['ShowFunctionFields'] boolean
    Defines whether or not MySQL functions fields should be initially displayed
    in edit/insert mode. Since version 2.10, the user can toggle this setting
    from the interface.
$cfg['ShowFieldTypesInDataEditView'] boolean
    Defines whether or not type fields should be initially displayed in edit/
    insert mode. The user can toggle this setting from the interface.
$cfg['CharEditing'] string
    Defines which type of editing controls should be used for CHAR and VARCHAR
    columns. Possible values are:
      + input - this allows to limit size of text to size of columns in MySQL,
        but has problems with newlines in columns
      + textarea - no problems with newlines in columns, but also no length
        limitations
    Default is old behavior so input.
$cfg['InsertRows'] integer
    Defines the maximum number of concurrent entries for the Insert page.
$cfg['ForeignKeyMaxLimit'] integer
    If there are fewer items than this in the set of foreign keys, then a
    drop-down box of foreign keys is presented, in the style described by the
    $cfg['ForeignKeyDropdownOrder'] setting.
$cfg['ForeignKeyDropdownOrder'] array
    For the foreign key drop-down fields, there are several methods of display,
    offering both the key and value data. The contents of the array should be
    one or both of the following strings: 'content-id', 'id-content'.
$cfg['ZipDump'] boolean
    $cfg['GZipDump'] boolean
    $cfg['BZipDump'] boolean
    Defines whether to allow the use of zip/GZip/BZip2 compression when
    creating a dump file
$cfg['CompressOnFly'] boolean
    Defines whether to allow on the fly compression for GZip/BZip2 compressed
    exports. This doesn't affect smaller dumps and allows users to create
    larger dumps that won't otherwise fit in memory due to php memory limit.
    Produced files contain more GZip/BZip2 headers, but all normal programs
    handle this correctly.
$cfg['LightTabs'] boolean
    If set to TRUE, use less graphically intense tabs on the top of the
    mainframe.
$cfg['PropertiesIconic'] string
    If set to TRUE, will display icons instead of text for db and table
    properties links (like 'Browse', 'Select', 'Insert', ...).
    Can be set to 'both' if you want icons AND text.
    When set to FALSE, will only show text.
$cfg['PropertiesNumColumns'] integer
    How many columns will be utilized to display the tables on the database
    property view? Default is 1 column. When setting this to a value larger
    than 1, the type of the database will be omitted for more display space.
$cfg['DefaultTabServer'] string
    Defines the tab displayed by default on server view. Possible values:
    "main.php" (recommended for multi-user setups), "server_databases.php",
    "server_status.php", "server_variables.php", "server_privileges.php" or
    "server_processlist.php".
$cfg['DefaultTabDatabase'] string
    Defines the tab displayed by default on database view. Possible values:
    "db_structure.php", "db_sql.php" or "db_search.php".
$cfg['DefaultTabTable'] string
    Defines the tab displayed by default on table view. Possible values:
    "tbl_structure.php", "tbl_sql.php", "tbl_select.php", "tbl_change.php" or
    "sql.php".
$cfg['MySQLManualBase'] string
    If set to an URL which points to the MySQL documentation (type depends on
    $cfg['MySQLManualType']), appropriate help links are generated.
    See MySQL Documentation page for more information about MySQL manuals and
    their types.
$cfg['MySQLManualType'] string
    Type of MySQL documentation:
      + viewable - "viewable online", current one used on MySQL website
      + searchable - "Searchable, with user comments"
      + chapters - "HTML, one page per chapter"
      + big - "HTML, all on one page"
      + none - do not show documentation links
$cfg['DefaultLang'] string
    Defines the default language to use, if not browser-defined or
    user-defined.
    The corresponding language file needs to be in locale/code/LC_MESSAGES/
    phpmyadmin.mo.
$cfg['DefaultConnectionCollation'] string
    Defines the default connection collation to use, if not user-defined.
    See the MySQL documentation for list of possible values.
$cfg['Lang'] string
    Force language to use.
    The corresponding language file needs to be in locale/code/LC_MESSAGES/
    phpmyadmin.mo.
$cfg['FilterLanguages'] string
    Limit list of available languages to those matching the given regular
    expression. For example if you want only Czech and English, you should set
    filter to '^(cs|en)'.
$cfg['RecodingEngine'] string
    You can select here which functions will be used for character set
    conversion. Possible values are:
      + auto - automatically use available one (first is tested iconv, then
        recode)
      + iconv - use iconv or libiconv functions
      + recode - use recode_string function
      + none - disable encoding conversion
    Default is auto.
    Enabled charset conversion activates a pull-down menu in the Export and
    Import pages, to choose the character set when exporting a file. The
    default value in this menu comes from $cfg['Export']['charset'] and $cfg
    ['Import']['charset'].
$cfg['IconvExtraParams'] string
    Specify some parameters for iconv used in charset conversion. See iconv
    documentation for details. By default //TRANSLIT is used, so that invalid
    characters will be transliterated.
$cfg['AvailableCharsets'] array
    Available character sets for MySQL conversion. You can add your own (any of
    supported by recode/iconv) or remove these which you don't use. Character
    sets will be shown in same order as here listed, so if you frequently use
    some of these move them to the top.
$cfg['TrustedProxies'] array
    Lists proxies and HTTP headers which are trusted for IP Allow/Deny. This
    list is by default empty, you need to fill in some trusted proxy servers if
    you want to use rules for IP addresses behind proxy.

    The following example specifies that phpMyAdmin should trust a
    HTTP_X_FORWARDED_FOR (X-Forwarded-For) header coming from the proxy
    1.2.3.4:

    $cfg['TrustedProxies'] =
         array('1.2.3.4' => 'HTTP_X_FORWARDED_FOR');

    The $cfg['Servers'][$i]['AllowDeny']['rules'] directive uses the client's
    IP address as usual.
$cfg['GD2Available'] string
    Specifies whether GD >= 2 is available. If yes it can be used for MIME
    transformations.
    Possible values are:
      + auto - automatically detect, this is a bit expensive operation for php
        < 4.3.0 so it is preferred to change this according to your server real
        possibilities
      + yes - GD 2 functions can be used
      + no - GD 2 function cannot be used
    Default is auto.
$cfg['CheckConfigurationPermissions'] boolean
    We normally check the permissions on the configuration file to ensure it's
    not world writable. However, phpMyAdmin could be installed on a NTFS
    filesystem mounted on a non-Windows server, in which case the permissions
    seems wrong but in fact cannot be detected. In this case a sysadmin would
    set this parameter to FALSE. Default is TRUE.
$cfg['LinkLengthLimit'] integer
    Limit for length of URL in links. When length would be above this limit, it
    is replaced by form with button. This is required as some web servers (IIS)
    have problems with long URLs. Default is 1000.
$cfg['NaviWidth'] integer
    Navi frame width in pixels. See themes/themename/layout.inc.php.
$cfg['NaviBackground'] string [CSS color for background]
    $cfg['MainBackground'] string [CSS color for background]
    The background styles used for both the frames. See themes/themename/
    layout.inc.php.
$cfg['NaviPointerBackground'] string [CSS color for background]
    $cfg['NaviPointerColor'] string [CSS color]
    The style used for the pointer in the navi frame. See themes/themename/
    layout.inc.php.
$cfg['LeftPointerEnable'] boolean
    A value of TRUE activates the navi pointer (when LeftFrameLight is FALSE).
$cfg['Border'] integer
    The size of a table's border. See themes/themename/layout.inc.php.
$cfg['ThBackground'] string [CSS color for background]
    $cfg['ThColor'] string [CSS color]
    The style used for table headers. See themes/themename/layout.inc.php.
$cfg['BgOne'] string [CSS color]
    The color (HTML) #1 for table rows. See themes/themename/layout.inc.php.
$cfg['BgTwo'] string [CSS color]
    The color (HTML) #2 for table rows. See themes/themename/layout.inc.php.
$cfg['BrowsePointerBackground'] string [CSS color]
    $cfg['BrowsePointerColor'] string [CSS color]
    $cfg['BrowseMarkerBackground'] string [CSS color]
    $cfg['BrowseMarkerColor'] string [CSS color]
    The colors (HTML) uses for the pointer and the marker in browse mode.
    The former feature highlights the row over which your mouse is passing and
    the latter lets you visually mark/unmark rows by clicking on them.
    Highlighting / marking a column is done by hovering over / clicking the
    column's header (outside of the text).
    See themes/themename/layout.inc.php.
$cfg['FontFamily'] string
    You put here a valid CSS font family value, for example arial, sans-serif.
    See themes/themename/layout.inc.php.
$cfg['FontFamilyFixed'] string
    You put here a valid CSS font family value, for example monospace. This one
    is used in textarea.
    See themes/themename/layout.inc.php.
$cfg['BrowsePointerEnable'] boolean
    Whether to activate the browse pointer or not.
$cfg['BrowseMarkerEnable'] boolean
    Whether to activate the browse marker or not.
$cfg['TextareaCols'] integer
    $cfg['TextareaRows'] integer
    $cfg['CharTextareaCols'] integer
    $cfg['CharTextareaRows'] integer
    Number of columns and rows for the textareas.
    This value will be emphasized (*2) for SQL query textareas and (*1.25) for
    SQL textareas inside the query window.
    The Char* values are used for CHAR and VARCHAR editing (if configured via
    $cfg['CharEditing']).
$cfg['LongtextDoubleTextarea'] boolean
    Defines whether textarea for LONGTEXT columns should have double size.
$cfg['TextareaAutoSelect'] boolean
    Defines if the whole textarea of the query box will be selected on click.
$cfg['LimitChars'] integer
    Maximum number of characters shown in any non-numeric field on browse view.
    Can be turned off by a toggle button on the browse page.
$cfg['ModifyDeleteAtLeft'] boolean $cfg['ModifyDeleteAtRight'] boolean
    Defines the place where table row links (Edit, Inline edit, Copy, Delete)
    would be put when tables contents are displayed (you may have them
    displayed both at the left and at the right). "Left" and "right" are parsed
    as "top" and "bottom" with vertical display mode.
$cfg['DefaultDisplay'] string
    There are 3 display modes: horizontal, horizontalflipped and vertical.
    Define which one is displayed by default. The first mode displays each row
    on a horizontal line, the second rotates the headers by 90 degrees, so you
    can use descriptive headers even though columns only contain small values
    and still print them out. The vertical mode sorts each row on a vertical
    lineup.
$cfg['HeaderFlipType'] string
    The HeaderFlipType can be set to 'auto', 'css' or 'fake'. When using 'css'
    the rotation of the header for horizontalflipped is done via CSS. The CSS
    transformation currently works only in Internet Explorer.If set to 'fake'
    PHP does the transformation for you, but of course this does not look as
    good as CSS. The 'auto' option enables CSS transformation when browser
    supports it and use PHP based one otherwise.
$cfg['DefaultPropDisplay'] string or integer
    When editing/creating new columns in a table all fields normally get lined
    up one field a line. (default: 'horizontal'). If you set this to 'vertical'
    you can have each field lined up vertically beneath each other. You can
    save up a lot of place on the horizontal direction and no longer have to
    scroll. If you set this to integer, editing of fewer columns will appear in
    'vertical' mode, while editing of more columns still in 'horizontal' mode.
    This way you can still effectively edit large number of columns, while
    having full view on few of them.
$cfg['ShowBrowseComments'] boolean
    $cfg['ShowPropertyComments'] boolean
    By setting the corresponding variable to TRUE you can enable the display of
    column comments in Browse or Property display. In browse mode, the comments
    are shown inside the header. In property mode, comments are displayed using
    a CSS-formatted dashed-line below the name of the column. The comment is
    shown as a tool-tip for that column.
$cfg['SQLQuery']['Edit'] boolean
    Whether to display an edit link to change a query in any SQL Query box.
$cfg['SQLQuery']['Explain'] boolean
    Whether to display a link to explain a SELECT query in any SQL Query box.
$cfg['SQLQuery']['ShowAsPHP'] boolean
    Whether to display a link to wrap a query in PHP code in any SQL Query box.
$cfg['SQLQuery']['Validate'] boolean
    Whether to display a link to validate a query in any SQL Query box. See
    also $cfg_SQLValidator.
$cfg['SQLQuery']['Refresh'] boolean
    Whether to display a link to refresh a query in any SQL Query box.
$cfg['UploadDir'] string
    The name of the directory where SQL files have been uploaded by other means
    than phpMyAdmin (for example, ftp). Those files are available under a
    drop-down box when you click the database or table name, then the Import
    tab.

    If you want different directory for each user, %u will be replaced with
    username.

    Please note that the file names must have the suffix ".sql" (or ".sql.bz2"
    or ".sql.gz" if support for compressed formats is enabled).

    This feature is useful when your file is too big to be uploaded via HTTP,
    or when file uploads are disabled in PHP.

    Please note that if PHP is running in safe mode, this directory must be
    owned by the same user as the owner of the phpMyAdmin scripts.

    See also FAQ 1.16 for alternatives.
$cfg['SaveDir'] string
    The name of the directory where dumps can be saved.

    If you want different directory for each user, %u will be replaced with
    username.

    Please note that the directory must exist and has to be writable for the
    user running webserver.

    Please note that if PHP is running in safe mode, this directory must be
    owned by the same user as the owner of the phpMyAdmin scripts.
$cfg['TempDir'] string
    The name of the directory where temporary files can be stored.

    This is needed for native MS Excel export, see FAQ 6.23 and to work around
    limitations of open_basedir for uploaded files, see FAQ 1.11.

    If the directory where phpMyAdmin is installed is subject to an
    open_basedir restriction, you need to create a temporary directory in some
    directory accessible by the web server. However for security reasons, this
    directory should be outside the tree published by webserver. If you cannot
    avoid having this directory published by webserver, place at least an empty
    index.html file there, so that directory listing is not possible.

    This directory should have as strict permissions as possible as the only
    user required to access this directory is the one who runs the webserver.
    If you have root privileges, simply make this user owner of this directory
    and make it accessible only by it:


    chown www-data:www-data tmp
    chmod 700 tmp

    If you cannot change owner of the directory, you can achieve a similar
    setup using ACL:

    chmod 700 tmp
    setfacl -m "g:www-data:rwx" tmp
    setfacl -d -m "g:www-data:rwx" tmp

    If neither of above works for you, you can still make the directory chmod
    777, but it might impose risk of other users on system reading and writing
    data in this directory.
$cfg['Export'] array
    In this array are defined default parameters for export, names of items are
    similar to texts seen on export page, so you can easily identify what they
    mean.
$cfg['Export']['method'] string
    Defines how the export form is displayed when it loads. Valid values are:
      + quick to display the minimum number of options to configure
      + custom to display every available option to configure
      + custom-no-form same as custom but does not display the option of using
        quick export
$cfg['Import'] array
    In this array are defined default parameters for import, names of items are
    similar to texts seen on import page, so you can easily identify what they
    mean.
$cfg['RepeatCells'] integer
    Repeat the headers every X cells, or 0 to deactivate.
$cfg['EditInWindow'] boolean
    $cfg['QueryWindowWidth'] integer
    $cfg['QueryWindowHeight'] integer
    $cfg['QueryHistoryDB'] boolean
    $cfg['QueryWindowDefTab'] string
    $cfg['QueryHistoryMax'] integer
    All those variables affect the query window feature. A SQL link or icon is
    always displayed on the left panel. If JavaScript is enabled in your
    browser, a click on this opens a distinct query window, which is a direct
    interface to enter SQL queries. Otherwise, the right panel changes to
    display a query box.

    The size of this query window can be customized with $cfg
    ['QueryWindowWidth'] and $cfg['QueryWindowHeight'] - both integers for the
    size in pixels. Note that normally, those parameters will be modified in
    layout.inc.php for the theme you are using.

    If $cfg['EditInWindow'] is set to true, a click on [Edit] from the results
    page (in the "Showing Rows" section) opens the query window and puts the
    current query inside it. If set to false, clicking on the link puts the SQL
    query in the right panel's query box.

    The usage of the JavaScript query window is recommended if you have a
    JavaScript enabled browser. Basic functions are used to exchange quite a
    few variables, so most 4th generation browsers should be capable to use
    that feature. It currently is only tested with Internet Explorer 6 and
    Mozilla 1.x.

    If $cfg['QueryHistoryDB'] is set to TRUE, all your Queries are logged to a
    table, which has to be created by you (see $cfg['Servers'][$i]['history']).
    If set to FALSE, all your queries will be appended to the form, but only as
    long as your window is opened they remain saved.

    When using the JavaScript based query window, it will always get updated
    when you click on a new table/db to browse and will focus if you click on
    "Edit SQL" after using a query. You can suppress updating the query window
    by checking the box "Do not overwrite this query from outside the window"
    below the query textarea. Then you can browse tables/databases in the
    background without losing the contents of the textarea, so this is
    especially useful when composing a query with tables you first have to look
    in. The checkbox will get automatically checked whenever you change the
    contents of the textarea. Please uncheck the button whenever you definitely
    want the query window to get updated even though you have made alterations.

    If $cfg['QueryHistoryDB'] is set to TRUE you can specify the amount of
    saved history items using $cfg['QueryHistoryMax'].

    The query window also has a custom tabbed look to group the features. Using
    the variable $cfg['QueryWindowDefTab'] you can specify the default tab to
    be used when opening the query window. It can be set to either 'sql',
    'files', 'history' or 'full'.
$cfg['BrowseMIME'] boolean
    Enable MIME-transformations.
$cfg['MaxExactCount'] integer
    For InnoDB tables, determines for how large tables phpMyAdmin should get
    the exact row count using SELECT COUNT. If the approximate row count as
    returned by SHOW TABLE STATUS is smaller than this value, SELECT COUNT will
    be used, otherwise the approximate count will be used.
$cfg['MaxExactCountViews'] integer
    For VIEWs, since obtaining the exact count could have an impact on
    performance, this value is the maximum to be displayed, using a SELECT
    COUNT ... LIMIT. The default value of 0 bypasses any row counting.
$cfg['NaturalOrder'] boolean
    Sorts database and table names according to natural order (for example, t1,
    t2, t10). Currently implemented in the left panel (Light mode) and in
    Database view, for the table list.
$cfg['InitialSlidersState'] string
    If set to 'closed', the visual sliders are initially in a closed state. A
    value of 'open' does the reverse. To completely disable all visual sliders,
    use 'disabled'.
$cfg['UserprefsDisallow'] array
    Contains names of configuration options (keys in $cfg array) that users
    can't set through user preferences. For possible values, refer to libraries
    /config/user_preferences.forms.php.
$cfg['TitleTable'] string
$cfg['TitleDatabase'] string
$cfg['TitleServer'] string
$cfg['TitleDefault'] string
    Allows you to specify window's title bar. You can use format string
    expansion.
$cfg['ErrorIconic'] boolean
    Uses icons for warnings, errors and informations.
$cfg['MainPageIconic'] boolean
    Uses icons on main page in lists and menu tabs.
$cfg['ReplaceHelpImg'] boolean
    Shows a help button instead of the "Documentation" message.
$cfg['ThemePath'] string
    If theme manager is active, use this as the path of the subdirectory
    containing all the themes.
$cfg['ThemeManager'] boolean
    Enables user-selectable themes. See FAQ 2.7.
$cfg['ThemeDefault'] string
    The default theme (a subdirectory under cfg['ThemePath']).
$cfg['ThemePerServer'] boolean
    Whether to allow different theme for each server.
$cfg['DefaultQueryTable'] string
    $cfg['DefaultQueryDatabase'] string
    Default queries that will be displayed in query boxes when user didn't
    specify any. You can use standard format string expansion.
$cfg['SQP']['fmtType'] string [html|none]
    The main use of the new SQL Parser is to pretty-print SQL queries. By
    default we use HTML to format the query, but you can disable this by
    setting this variable to 'none'.
$cfg['SQP']['fmtInd'] float
    $cfg['SQP']['fmtIndUnit'] string [em|px|pt|ex]
    For the pretty-printing of SQL queries, under some cases the part of a
    query inside a bracket is indented. By changing $cfg['SQP']['fmtInd'] you
    can change the amount of this indent.
    Related in purpose is $cfg['SQP']['fmtIndUnit'] which specifies the units
    of the indent amount that you specified. This is used via stylesheets.
$cfg['SQP']['fmtColor'] array of string tuples
    This array is used to define the colours for each type of element of the
    pretty-printed SQL queries. The tuple format is
    class => [HTML colour code | empty string]
    If you specify an empty string for the color of a class, it is ignored in
    creating the stylesheet. You should not alter the class names, only the
    colour strings.
    Class name key:
      + comment Applies to all comment sub-classes
      + comment_mysql Comments as "#...\n"
      + comment_ansi Comments as "-- ...\n"
      + comment_c Comments as "/*...*/"
      + digit Applies to all digit sub-classes
      + digit_hex Hexadecimal numbers
      + digit_integer Integer numbers
      + digit_float Floating point numbers
      + punct Applies to all punctuation sub-classes

Transformations

 1. Introduction
 2. Usage
 3. File structure

1. Introduction

To enable transformations, you have to setup the column_info table and the
proper directives. Please see the Configuration section on how to do so.

You can apply different transformations to the contents of each column. The
transformation will take the content of each column and transform it with
certain rules defined in the selected transformation.

Say you have a column 'filename' which contains a filename. Normally you would
see in phpMyAdmin only this filename. Using transformations you can transform
that filename into a HTML link, so you can click inside of the phpMyAdmin
structure on the column's link and will see the file displayed in a new browser
window. Using transformation options you can also specify strings to append/
prepend to a string or the format you want the output stored in.

For a general overview of all available transformations and their options, you
can consult your <www.your-host.com>/<your-install-dir>/
transformation_overview.php installation.

For a tutorial on how to effectively use transformations, see our Link section
on the official phpMyAdmin homepage.

2. Usage

Go to your tbl_structure.php page (i.e. reached through clicking on the
'Structure' link for a table). There click on "Change" (or change icon) and
there you will see three new fields at the end of the line. They are called
'MIME-type', 'Browser transformation' and 'Transformation options'.

  * The field 'MIME-type' is a drop-down field. Select the MIME-type that
    corresponds to the column's contents. Please note that transformations are
    inactive as long as no MIME-type is selected.
  * The field 'Browser transformation' is a drop-down field. You can choose
    from a hopefully growing amount of pre-defined transformations. See below
    for information on how to build your own transformation.
    There are global transformations and mimetype-bound transformations. Global
    transformations can be used for any mimetype. They will take the mimetype,
    if necessary, into regard. Mimetype-bound transformations usually only
    operate on a certain mimetype. There are transformations which operate on
    the main mimetype (like 'image'), which will most likely take the subtype
    into regard, and those who only operate on a specific subtype (like 'image/
    jpeg').
    You can use transformations on mimetypes for which the function was not
    defined for. There is no security check for you selected the right
    transformation, so take care of what the output will be like.
  * The field 'Transformation options' is a free-type textfield. You have to
    enter transform-function specific options here. Usually the transforms can
    operate with default options, but it is generally a good idea to look up
    the overview to see which options are necessary.
    Much like the ENUM/SET-Fields, you have to split up several options using
    the format 'a','b','c',...(NOTE THE MISSING BLANKS). This is because
    internally the options will be parsed as an array, leaving the first value
    the first element in the array, and so forth.
    If you want to specify a MIME character set you can define it in the
    transformation_options. You have to put that outside of the pre-defined
    options of the specific mime-transform, as the last value of the set. Use
    the format "'; charset=XXX'". If you use a transform, for which you can
    specify 2 options and you want to append a character set, enter "'first
    parameter','second parameter','charset=us-ascii'". You can, however use the
    defaults for the parameters: "'','','charset=us-ascii'".

3. File structure

All mimetypes and their transformations are defined through single files in the
directory 'libraries/transformations/'.

They are stored in files to ease up customization and easy adding of new
transformations.

Because the user cannot enter own mimetypes, it is kept sure that
transformations always work. It makes no sense to apply a transformation to a
mimetype the transform-function doesn't know to handle.

One can, however, use empty mime-types and global transformations which should
work for many mimetypes. You can also use transforms on a different mimetype
than what they where built for, but pay attention to option usage as well as
what the transformation does to your column.

There is a basic file called 'global.inc.php'. This function can be included by
any other transform function and provides some basic functions.

There are 5 possible file names:

 1. A mimetype+subtype transform:

    [mimetype]_[subtype]__[transform].inc.php

    Please not that mimetype and subtype are separated via '_', which shall not
    be contained in their names. The transform function/filename may contain
    only characters which cause no problems in the file system as well as the
    PHP function naming convention.

    The transform function will the be called 'PMA_transform_[mimetype]_
    [subtype]__[transform]()'.

    Example:

    text_html__formatted.inc.php
    PMA_transform_text_html__formatted()
 2. A mimetype (w/o subtype) transform:

    [mimetype]__[transform].inc.php

    Please note that there are no single '_' characters. The transform function
    /filename may contain only characters which cause no problems in the file
    system as well as the PHP function naming convention.

    The transform function will the be called 'PMA_transform_[mimetype]__
    [transform]()'.

    Example:

    text__formatted.inc.php
    PMA_transform_text__formatted()
 3. A mimetype+subtype without specific transform function

    [mimetype]_[subtype].inc.php

    Please note that there are no '__' characters in the filename. Do not use
    special characters in the filename causing problems with the file system.

    No transformation function is defined in the file itself.

    Example:

    text_plain.inc.php
    (No function)
 4. A mimetype (w/o subtype) without specific transform function

    [mimetype].inc.php

    Please note that there are no '_' characters in the filename. Do not use
    special characters in the filename causing problems with the file system.

    No transformation function is defined in the file itself.

    Example:

    text.inc.php
    (No function)
 5. A global transform function with no specific mimetype

    global__[transform].inc.php

    The transform function will the be called 'PMA_transform_global__
    [transform]()'.

    Example:

    global__formatted
    PMA_transform_global__formatted()

So generally use '_' to split up mimetype and subtype, and '__' to provide a
transform function.

All filenames containing no '__' in themselves are not shown as valid transform
functions in the dropdown.

Please see the libraries/transformations/TEMPLATE file for adding your own
transform function. See the libraries/transformations/TEMPLATE_MIMETYPE for
adding a mimetype without a transform function.

To create a new transform function please see libraries/transformations/
template_generator.sh. To create a new, empty mimetype please see libraries/
transformations/template_generator_mimetype.sh.

A transform function always gets passed three variables:

 1. $buffer - Contains the text inside of the column. This is the text, you
    want to transform.
 2. $options - Contains any user-passed options to a transform function as an
    array.
 3. $meta - Contains an object with information about your column. The data is
    drawn from the output of the mysql_fetch_field() function. This means, all
    object properties described on the manual page are available in this
    variable and can be used to transform a column accordingly to unsigned/
    zerofill/not_null/... properties.
    The $meta->mimetype variable contains the original MIME-type of the column
    (i.e. 'text/plain', 'image/jpeg' etc.)

Additionally you should also provide additional function to provide information
about the transformation to the user. This function should have same name as
transformation function just with appended _info suffix. This function accepts
no parameters and returns array with information about the transformation.
Currently following keys can be used:

info
    Long description of the transformation.

Server

1.1 My server is crashing each time a specific action is required or phpMyAdmin
sends a blank page or a page full of cryptic characters to my browser, what can
I do?

Try to set the $cfg['OBGzip'] directive to FALSE in your config.inc.php file
and the zlib.output_compression directive to Off in your php configuration
file.

1.2 My Apache server crashes when using phpMyAdmin.

You should first try the latest versions of Apache (and possibly MySQL).
See also the FAQ 1.1 entry about PHP bugs with output buffering.
If your server keeps crashing, please ask for help in the various Apache
support groups.

1.3 (withdrawn).

1.4 Using phpMyAdmin on IIS, I'm displayed the error message: "The specified
CGI application misbehaved by not returning a complete set of HTTP headers
...".

You just forgot to read the install.txt file from the php distribution. Have a
look at the last message in this bug report from the official PHP bug database.

1.5 Using phpMyAdmin on IIS, I'm facing crashes and/or many error messages with
the HTTP.

This is a known problem with the PHP ISAPI filter: it's not so stable. Please
use instead the cookie authentication mode.

1.6 I can't use phpMyAdmin on PWS: nothing is displayed!

This seems to be a PWS bug. Filippo Simoncini found a workaround (at this time
there is no better fix): remove or comment the DOCTYPE declarations (2 lines)
from the scripts libraries/header.inc.php, libraries/header_printview.inc.php,
index.php, navigation.php and libraries/common.lib.php.

1.7 How can I GZip or Bzip a dump or a CSV export? It does not seem to work.

These features are based on the gzencode() and bzcompress() PHP functions to be
more independent of the platform (Unix/Windows, Safe Mode or not, and so on).
So, you must have Zlib/Bzip2 support (--with-zlib and --with-bz2).

1.8 I cannot insert a text file in a table, and I get an error about safe mode
being in effect.

Your uploaded file is saved by PHP in the "upload dir", as defined in php.ini
by the variable upload_tmp_dir (usually the system default is /tmp).
We recommend the following setup for Apache servers running in safe mode, to
enable uploads of files while being reasonably secure:

  * create a separate directory for uploads: mkdir /tmp/php
  * give ownership to the Apache server's user.group: chown apache.apache /tmp/
    php
  * give proper permission: chmod 600 /tmp/php
  * put upload_tmp_dir = /tmp/php in php.ini
  * restart Apache

1.9 (withdrawn).

1.10 I'm having troubles when uploading files with phpMyAdmin running on a
secure server. My browser is Internet Explorer and I'm using the Apache server.

As suggested by "Rob M" in the phpWizard forum, add this line to your
httpd.conf:

SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown

It seems to clear up many problems between Internet Explorer and SSL.

1.11 I get an 'open_basedir restriction' while uploading a file from the query
box.

Since version 2.2.4, phpMyAdmin supports servers with open_basedir
restrictions. However you need to create temporary directory and configure it
as $cfg['TempDir']. The uploaded files will be moved there, and after execution
of your SQL commands, removed.

1.12 I have lost my MySQL root password, what can I do?

The MySQL manual explains how to reset the permissions.

1.13 (withdrawn).

1.14 (withdrawn).

1.15 I have problems with mysql.user column names.

In previous MySQL versions, the User and Passwordcolumns were named user and
password. Please modify your column names to align with current standards.

1.16 I cannot upload big dump files (memory, HTTP or timeout problems).

Starting with version 2.7.0, the import engine has been re?written and these
problems should not occur. If possible, upgrade your phpMyAdmin to the latest
version to take advantage of the new import features.

The first things to check (or ask your host provider to check) are the values
of upload_max_filesize, memory_limit and post_max_size in the php.ini
configuration file. All of these three settings limit the maximum size of data
that can be submitted and handled by PHP. One user also said that post_max_size
and memory_limit need to be larger than upload_max_filesize.

There exist several workarounds if your upload is too big or your hosting
provider is unwilling to change the settings:

  * Look at the $cfg['UploadDir'] feature. This allows one to upload a file to
    the server via scp, ftp, or your favorite file transfer method. PhpMyAdmin
    is then able to import the files from the temporary directory. More
    information is available in the Configuration section of this document.
  * Using a utility (such as BigDump) to split the files before uploading. We
    cannot support this or any third party applications, but are aware of users
    having success with it.
  * If you have shell (command line) access, use MySQL to import the files
    directly. You can do this by issuing the "source" command from within
    MySQL: source filename.sql.

1.17 Which MySQL versions does phpMyAdmin support?

Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For older
MySQL versions, you need to use the latest 2.x branch. phpMyAdmin can connect
to your MySQL server using PHP's classic MySQL extension as well as the
improved MySQL extension (MySQLi) that is available in php 5.0. The latter one
should be used unless you have a good reason not to do so.
When compiling PHP, we strongly recommend that you manually link the MySQL
extension of your choice to a MySQL client library of at least the same minor
version since the one that is bundled with some PHP distributions is rather old
and might cause problems (see FAQ 1.17a).

MariaDB is also supported (versions 5.1 and 5.2 were tested).

1.17a I cannot connect to the MySQL server. It always returns the error
message, "Client does not support authentication protocol requested by server;
consider upgrading MySQL client"

You tried to access MySQL with an old MySQL client library. The version of your
MySQL client library can be checked in your phpinfo() output. In general, it
should have at least the same minor version as your server - as mentioned in
FAQ 1.17.

This problem is generally caused by using MySQL version 4.1 or newer. MySQL
changed the authentication hash and your PHP is trying to use the old method.
The proper solution is to use the mysqli extension with the proper client
library to match your MySQL installation. Your chosen extension is specified in
$cfg['Servers'][$i]['extension']. More information (and several workarounds)
are located in the MySQL Documentation.

1.18 (withdrawn).

1.19 I can't run the "display relations" feature because the script seems not
to know the font face I'm using!

The "FPDF" library we're using for this feature requires some special files to
use font faces.
Please refers to the FPDF manual to build these files.

1.20 I receive the error "cannot load MySQL extension, please check PHP
Configuration".

To connect to a MySQL server, PHP needs a set of MySQL functions called "MySQL
extension". This extension may be part of the PHP distribution (compiled-in),
otherwise it needs to be loaded dynamically. Its name is probably mysql.so or
php_mysql.dll. phpMyAdmin tried to load the extension but failed.

Usually, the problem is solved by installing a software package called
"PHP-MySQL" or something similar.

1.21 I am running the CGI version of PHP under Unix, and I cannot log in using
cookie auth.

In php.ini, set mysql.max_links higher than 1.

1.22 I don't see the "Location of text file" field, so I cannot upload.

This is most likely because in php.ini, your file_uploads parameter is not set
to "on".

1.23 I'm running MySQL on a Win32 machine. Each time I create a new table the
table and column names are changed to lowercase!

This happens because the MySQL directive lower_case_table_names defaults to 1
(ON) in the Win32 version of MySQL. You can change this behavior by simply
changing the directive to 0 (OFF):
Just edit your my.ini file that should be located in your Windows directory and
add the following line to the group [mysqld]:

set-variable = lower_case_table_names=0

Next, save the file and restart the MySQL service. You can always check the
value of this directive using the query

SHOW VARIABLES LIKE 'lower_case_table_names';

1.24 (withdrawn).

1.25 I am running Apache with mod_gzip-1.3.26.1a on Windows XP, and I get
problems, such as undefined variables when I run a SQL query.

A tip from Jose Fandos: put a comment on the following two lines in httpd.conf,
like this:

# mod_gzip_item_include file \.php$
# mod_gzip_item_include mime "application/x-httpd-php.*"

as this version of mod_gzip on Apache (Windows) has problems handling PHP
scripts. Of course you have to restart Apache.

1.26 I just installed phpMyAdmin in my document root of IIS but I get the error
"No input file specified" when trying to run phpMyAdmin.

This is a permission problem. Right-click on the phpmyadmin folder and choose
properties. Under the tab Security, click on "Add" and select the user
"IUSR_machine" from the list. Now set his permissions and it should work.

1.27 I get empty page when I want to view huge page (eg. db_structure.php with
plenty of tables).

This is a PHP bug that occur when GZIP output buffering is enabled. If you turn
off it (by $cfg['OBGzip'] = false in config.inc.php), it should work. This bug
will be fixed in PHP 5.0.0.

1.28 My MySQL server sometimes refuses queries and returns the message
'Errorcode: 13'. What does this mean?

This can happen due to a MySQL bug when having database / table names with
upper case characters although lower_case_table_names is set to 1. To fix this,
turn off this directive, convert all database and table names to lower case and
turn it on again. Alternatively, there's a bug-fix available starting with
MySQL 3.23.56 / 4.0.11-gamma.

1.29 When I create a table or modify a column, I get an error and the columns
are duplicated.

It is possible to configure Apache in such a way that PHP has problems
interpreting .php files.

The problems occur when two different (and conflicting) set of directives are
used:

SetOutputFilter PHP
SetInputFilter PHP

and

AddType application/x-httpd-php .php

In the case we saw, one set of directives was in /etc/httpd/conf/httpd.conf,
while the other set was in /etc/httpd/conf/addon-modules/php.conf.
The recommended way is with AddType, so just comment out the first set of lines
and restart Apache:

#SetOutputFilter PHP
#SetInputFilter PHP

1.30 I get the error "navigation.php: Missing hash".

This problem is known to happen when the server is running Turck MMCache but
upgrading MMCache to version 2.3.21 solves the problem.

1.31 Does phpMyAdmin support php5?

Yes.

Since release 3.0 only PHP 5.2 and newer. For older PHP versions 2.9 branch is
still maintained.

1.32 Can I use HTTP authentication with IIS?

Yes. This procedure was tested with phpMyAdmin 2.6.1, PHP 4.3.9 in ISAPI mode
under IIS 5.1.

 1. In your php.ini file, set cgi.rfc2616_headers = 0
 2. In Web Site Properties -> File/Directory Security -> Anonymous Access
    dialog box, check the Anonymous access checkbox and uncheck any other
    checkboxes (i.e. uncheck Basic authentication, Integrated Windows
    authentication, and Digest if it's enabled.) Click OK.
 3. In Custom Errors, select the range of 401;1 through 401;5 and click the Set
    to Default button.

1.33 Is there a problem with the mysqli extension when running PHP 5.0.4 on
64-bit systems?

Yes. This problem affects phpMyAdmin ("Call to undefined function
pma_reloadnavigation"), so upgrade your PHP to the next version.

1.34 Can I access directly to database or table pages?

Yes. Out of the box, you can use URLs like http://server/phpMyAdmin/index.php?
server=X&db=database&table=table&target=script. For server you use the server
number which refers to the order of the server paragraph in config.inc.php.
Table and script parts are optional. If you want http://server/phpMyAdmin/
database[/table][/script] URLs, you need to do some configuration. Following
lines apply only for Apache web server. First make sure, that you have enabled
some features within global configuration. You need Options FollowSymLinks and
AllowOverride FileInfo enabled for directory where phpMyAdmin is installed and
you need mod_rewrite to be enabled. Then you just need to create following
.htaccess file in root folder of phpMyAdmin installation (don't forget to
change directory name inside of it):

RewriteEngine On
RewriteBase /path_to_phpMyAdmin
RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)/([a-z_]+\.php)$ index.php?db=$1&table=$2&target=$3 [R]
RewriteRule ^([a-zA-Z0-9_]+)/([a-z_]+\.php)$ index.php?db=$1&target=$2 [R]
RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)$ index.php?db=$1&table=$2 [R]
RewriteRule ^([a-zA-Z0-9_]+)$ index.php?db=$1 [R]

1.35 Can I use HTTP authentication with Apache CGI?

Yes. However you need to pass authentication variable to CGI using following
rewrite rule:

RewriteEngine On
RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization},L]

1.36 I get an error "500 Internal Server Error".

There can be many explanations to this and a look at your server's error log
file might give a clue.

1.37 I run phpMyAdmin on cluster of different machines and password encryption
in cookie auth doesn't work.

If your cluster consist of different architectures, PHP code used for
encryption/decryption won't work correct. This is caused by use of pack/unpack
functions in code. Only solution is to use mcrypt extension which works fine in
this case.

1.38 Can I use phpMyAdmin on a server on which Suhosin is enabled?

Yes but the default configuration values of Suhosin are known to cause problems
with some operations, for example editing a table with many columns and no
primary key or with textual primary key.

Suhosin configuration might lead to malfunction in some cases and it can not be
fully avoided as phpMyAdmin is kind of application which needs to transfer big
amounts of columns in single HTTP request, what is something what Suhosin tries
to prevent. Generally all suhosin.request.*, suhosin.post.* and suhosin.get.*
directives can have negative effect on phpMyAdmin usability. You can always
find in your error logs which limit did cause dropping of variable, so you can
diagnose the problem and adjust matching configuration variable.

The default values for most Suhosin configuration options will work in most
scenarios, however you might want to adjust at least following parameters:

  * suhosin.request.max_vars should be increased (eg. 2048)
  * suhosin.post.max_vars should be increased (eg. 2048)
  * suhosin.request.max_array_index_length should be increased (eg. 256)
  * suhosin.post.max_array_index_length should be increased (eg. 256)
  * suhosin.request.max_totalname_length should be increased (eg. 8192)
  * suhosin.post.max_totalname_length should be increased (eg. 8192)
  * suhosin.sql.bailout_on_error needs to be disabled (the default)
  * suhosin.log.* should not include SQL, otherwise you get big slowdown

You can also disable the warning using the SuhosinDisableWarning directive.

1.39 When I try to connect via https, I can log in, but then my connection is
redirected back to http. What can cause this behavior?

Be sure that you have enabled SSLOptions and StdEnvVars in your Apache
configuration. See http://httpd.apache.org/docs/2.0/mod/mod_ssl.html#ssloptions
.

1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does
not work.

To be able to use cookie auth Apache must know that it has to rewrite the
set-cookie headers.
Example from the Apache 2.2 documentation:

ProxyPass /mirror/foo/ http://backend.example.com/
ProxyPassReverse /mirror/foo/ http://backend.example.com/
ProxyPassReverseCookieDomain backend.example.com public.example.com
ProxyPassReverseCookiePath / /mirror/foo/

Note: if the backend url looks like http://host/~user/phpmyadmin, the tilde (~)
must be url encoded as %7E in the ProxyPassReverse* lines. This is not specific
to phpmyadmin, it's just the behavior of Apache.

ProxyPass /mirror/foo/ http://backend.example.com/~user/phpmyadmin
ProxyPassReverse /mirror/foo/
http://backend.example.com/%7Euser/phpmyadmin
ProxyPassReverseCookiePath /%7Euser/phpmyadmin /mirror/foo

See http://httpd.apache.org/docs/2.2/mod/mod_proxy.html for more details.

1.41 When I view a database and ask to see its privileges, I get an error about
an unknown column.

The MySQL server's privilege tables are not up to date, you need to run the
mysql_upgrade command on the server.

Configuration

2.1 The error message "Warning: Cannot add header information - headers already
sent by ..." is displayed, what's the problem?

Edit your config.inc.php file and ensure there is nothing (I.E. no blank lines,
no spaces, no characters...) neither before the <?php tag at the beginning,
neither after the ?> tag at the end. We also got a report from a user under
IIS, that used a zipped distribution kit: the file libraries/Config.class.php
contained an end-of-line character (hex 0A) at the end; removing this character
cleared his errors.

2.2 phpMyAdmin can't connect to MySQL. What's wrong?

Either there is an error with your PHP setup or your username/password is
wrong. Try to make a small script which uses mysql_connect and see if it works.
If it doesn't, it may be you haven't even compiled MySQL support into PHP.

2.3 The error message "Warning: MySQL Connection Failed: Can't connect to local
MySQL server through socket '/tmp/mysql.sock' (111) ..." is displayed. What can
I do?

For RedHat users, Harald Legner suggests this on the mailing list:

On my RedHat-Box the socket of MySQL is /var/lib/mysql/mysql.sock. In your
php.ini you will find a line

mysql.default_socket = /tmp/mysql.sock

change it to

mysql.default_socket = /var/lib/mysql/mysql.sock

Then restart apache and it will work.

Here is a fix suggested by Brad Ummer:

  * First, you need to determine what socket is being used by MySQL.
    To do this, telnet to your server and go to the MySQL bin directory. In
    this directory there should be a file named mysqladmin. Type ./mysqladmin
    variables, and this should give you a bunch of info about your MySQL
    server, including the socket (/tmp/mysql.sock, for example).
  * Then, you need to tell PHP to use this socket.
    To do this in phpMyAdmin, you need to complete the socket information in
    the config.inc.php.
    For example: $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';

    Please also make sure that the permissions of this file allow to be
    readable by your webserver (i.e. '0755').

Have also a look at the corresponding section of the MySQL documentation.

2.4 Nothing is displayed by my browser when I try to run phpMyAdmin, what can I
do?

Try to set the $cfg['OBGZip'] directive to FALSE in the phpMyAdmin
configuration file. It helps sometime.
Also have a look at your PHP version number: if it contains "4.0b..." it means
you're running a beta version of PHP. That's not a so good idea, please upgrade
to a plain revision.

2.5 Each time I want to insert or change a record or drop a database or a
table, an error 404 (page not found) is displayed or, with HTTP or cookie
authentication, I'm asked to log in again. What's wrong?

Check the value you set for the $cfg['PmaAbsoluteUri'] directive in the
phpMyAdmin configuration file.

2.6 I get an "Access denied for user: 'root@localhost' (Using password: YES)
"-error when trying to access a MySQL-Server on a host which is port-forwarded
for my localhost.

When you are using a port on your localhost, which you redirect via
port-forwarding to another host, MySQL is not resolving the localhost as
expected.
Erik Wasser explains: The solution is: if your host is "localhost" MySQL (the
command line tool mysql as well) always tries to use the socket connection for
speeding up things. And that doesn't work in this configuration with port
forwarding.
If you enter "127.0.0.1" as hostname, everything is right and MySQL uses the
TCP connection.

2.7 Using and creating themes

Themes are configured with $cfg['ThemePath'], $cfg['ThemeManager'] and $cfg
['ThemeDefault'].

Under $cfg['ThemePath'], you should not delete the directory "original" or its
underlying structure, because this is the system theme used by phpMyAdmin.
"original" contains all images and styles, for backwards compatibility and for
all themes that would not include images or css-files.

If $cfg['ThemeManager'] is enabled, you can select your favorite theme on the
main page. Your selected theme will be stored in a cookie.


To create a theme:

  * make a new subdirectory (for example "your_theme_name") under $cfg
    ['ThemePath'] (by default themes)
  * copy the files and directories from "original" to "your_theme_name"
  * edit the css-files in "your_theme_name/css"
  * put your new images in "your_theme_name/img"
  * edit layout.inc.php in "your_theme_name"
  * edit info.inc.php in "your_theme_name" to contain your chosen theme name,
    that will be visible in user interface
  * make a new screenshot of your theme and save it under "your_theme_name/
    screen.png"

In theme directory there is file info.inc.php which contains theme verbose
name, theme generation and theme version. These versions and generations are
enumerated from 1 and do not have any direct dependence on phpMyAdmin version.
Themes within same generation should be backwards compatible - theme with
version 2 should work in phpMyAdmin requiring version 1. Themes with different
generation are incompatible.

If you do not want to use your own symbols and buttons, remove the directory
"img" in "your_theme_name". phpMyAdmin will use the default icons and buttons
(from the system-theme "original").

2.8 I get "Missing parameters" errors, what can I do?

Here are a few points to check:

  * In config.inc.php, try to leave the $cfg['PmaAbsoluteUri'] directive empty.
    See also FAQ 4.7.
  * Maybe you have a broken PHP installation or you need to upgrade your Zend
    Optimizer. See http://bugs.php.net/bug.php?id=31134.
  * If you are using Hardened PHP with the ini directive
    varfilter.max_request_variables set to the default (200) or another low
    value, you could get this error if your table has a high number of columns.
    Adjust this setting accordingly. (Thanks to Klaus Dorninger for the hint).
  * In the php.ini directive arg_separator.input, a value of ";" will cause
    this error. Replace it with "&;".
  * If you are using Hardened-PHP, you might want to increase request limits.
  * The directory specified in the php.ini directive session.save_path does not
    exist or is read-only.

2.9 Seeing an upload progress bar

To be able to see a progress bar during your uploads, your server must have
either the APC extension or the uploadprogress one. Moreover, the JSON
extension has to be enabled in your PHP.

If using APC, you must set apc.rfc1867 to on in your php.ini.

Known limitations

3.1 When using HTTP authentication, a user who logged out can not log in again
in with the same nick.

This is related to the authentication mechanism (protocol) used by phpMyAdmin.
To bypass this problem: just close all the opened browser windows and then go
back to phpMyAdmin. You should be able to log in again.

3.2 When dumping a large table in compressed mode, I get a memory limit error
or a time limit error.

Compressed dumps are built in memory and because of this are limited to php's
memory limit. For GZip/BZip2 exports this can be overcome since 2.5.4 using
$cfg['CompressOnFly'] (enabled by default). Zip exports can not be handled this
way, so if you need Zip files for larger dump, you have to use another way.

3.3 With InnoDB tables, I lose foreign key relationships when I rename a table
or a column.

This is an InnoDB bug, see http://bugs.mysql.com/bug.php?id=21704.

3.4 I am unable to import dumps I created with the mysqldump tool bundled with
the MySQL server distribution.

The problem is that older versions of mysqldump created invalid comments like
this:

-- MySQL dump 8.22
--
-- Host: localhost Database: database
---------------------------------------------------------
-- Server version 3.23.54

The invalid part of the code is the horizontal line made of dashes that appears
once in every dump created with mysqldump. If you want to run your dump you
have to turn it into valid MySQL. This means, you have to add a whitespace
after the first two dashes of the line or add a # before it:
-- -------------------------------------------------------
or
#---------------------------------------------------------

3.5 When using nested folders there are some multiple hierarchies displayed in
a wrong manner?! ($cfg['LeftFrameTableSeparator'])

Please note that you should not use the separating string multiple times
without any characters between them, or at the beginning/end of your table
name. If you have to, think about using another TableSeparator or disabling
that feature

3.6 What is currently not supported in phpMyAdmin about InnoDB?

In Relation view, being able to choose a table in another database, or having
more than one index column in the foreign key.

In Query-by-example (Query), automatic generation of the query LEFT JOIN from
the foreign table.


3.7 I have table with many (100+) columns and when I try to browse table I get
series of errors like "Warning: unable to parse url". How can this be fixed?

Your table neither have a primary key nor an unique one, so we must use a long
expression to identify this row. This causes problems to parse_url function.
The workaround is to create a primary or unique key.

3.8 I cannot use (clickable) HTML-forms in columns where I put a
MIME-Transformation onto!

Due to a surrounding form-container (for multi-row delete checkboxes), no
nested forms can be put inside the table where phpMyAdmin displays the results.
You can, however, use any form inside of a table if keep the parent
form-container with the target to tbl_row_delete.php and just put your own
input-elements inside. If you use a custom submit input field, the form will
submit itself to the displaying page again, where you can validate the
$HTTP_POST_VARS in a transformation. For a tutorial on how to effectively use
transformations, see our Link section on the official phpMyAdmin-homepage.

3.9 I get error messages when using "--sql_mode=ANSI" for the MySQL server

When MySQL is running in ANSI-compatibility mode, there are some major
differences in how SQL is structured (see http://dev.mysql.com/doc/mysql/en/
ansi-mode.html). Most important of all, the quote-character (") is interpreted
as an identifier quote character and not as a string quote character, which
makes many internal phpMyAdmin operations into invalid SQL statements. There is
no workaround to this behaviour. News to this item will be posted in Bug report
#816858

3.10 Homonyms and no primary key: When the results of a SELECT display more
that one column with the same value (for example SELECT lastname from employees
where firstname like 'A%' and two "Smith" values are displayed), if I click
Edit I cannot be sure that I am editing the intended row.

Please make sure that your table has a primary key, so that phpMyAdmin can use
it for the Edit and Delete links.

3.11 The number of records for InnoDB tables is not correct.

phpMyAdmin uses a quick method to get the row count, and this method only
returns an approximate count in the case of InnoDB tables. See $cfg
['MaxExactCount'] for a way to modify those results, but this could have a
serious impact on performance.

3.12 (withdrawn).

3.13 I get an error when entering USE followed by a db name containing an
hyphen.

The tests I have made with MySQL 5.1.49 shows that the API does not accept this
syntax for the USE command.

3.14 I am not able to browse a table when I don't have the right to SELECT one
of the columns.

This has been a known limitation of phpMyAdmin since the beginning and it's not
likely to be solved in the future.

3.15 When I import an Excel spreadsheet, some cells with calculations do not
display correctly.

phpMyAdmin uses the PHPExcel library to parse Excel XLS and XLSX spreadsheets.
Therefore, any limitations that are listed on their page regarding Excel
calculations will also apply here.

PHPExcel will be kept up to date so as to make all improvements available to
phpMyAdmin users.

3.16 When I compress (gzip, bzip2, zip) an Excel workbook and attempt to import
it, nothing happens.

Since Excel XLSX workbooks are already compressed, there is often times only a
small benefit from compressing them yet again. Support for compressed Excel
XLSX and XLS workbooks may be added in the future.

3.17 When I import an Excel spreadsheet, my custom cell types are not
represented as they are in Excel.

Excel's internal representation of custom cell types is rather muddled
(especially in Excel 97-2003 binary XLS files). If possible, consider using a
built-in type. These are almost always guarenteed to import correctly.

3.18 When I import a CSV file that contains multiple tables, they are lumped
together into a single table.

There is no reliable way to differetiate tables in CSV format. For the time
being, you will have to break apart CSV files containing multiple tables.

3.19 When I import a file and have phpMyAdmin determine the appropriate data
structure it only uses int, decimal, and varchar types.

Currently, the import type-detection system can only assign these MySQL types
to columns. In future, more will likely be added but for the time being you
will have to edit the structure to your liking post-import.

Also, you should note the fact that phpMyAdmin will use the size of the largest
item in any given column as the column size for the appropriate type. If you
know you will be adding larger items to that column then you should manually
adjust the column sizes accordingly. This is done for the sake of efficiency.

ISPs, multi-user installations

4.1 I'm an ISP. Can I setup one central copy of phpMyAdmin or do I need to
install it for each customer.

Since version 2.0.3, you can setup a central copy of phpMyAdmin for all your
users. The development of this feature was kindly sponsored by NetCologne GmbH.
This requires a properly setup MySQL user management and phpMyAdmin HTTP or
cookie authentication. See the install section on "Using HTTP authentication".

4.2 What's the preferred way of making phpMyAdmin secure against evil access.

This depends on your system.
If you're running a server which cannot be accessed by other people, it's
sufficient to use the directory protection bundled with your webserver (with
Apache you can use .htaccess files, for example).
If other people have telnet access to your server, you should use phpMyAdmin's
HTTP or cookie authentication features.

Suggestions:

  * Your config.inc.php file should be chmod 660.
  * All your phpMyAdmin files should be chown -R phpmy.apache, where phpmy is a
    user whose password is only known to you, and apache is the group under
    which Apache runs.
  * You should use PHP safe mode, to protect from other users that try to
    include your config.inc.php in their scripts.

4.3 I get errors about not being able to include a file in /lang or in /
libraries.

Check php.ini, or ask your sysadmin to check it. The include_path must contain
"." somewhere in it, and open_basedir, if used, must contain "." and "./lang"
to allow normal operation of phpMyAdmin.

4.4 phpMyAdmin always gives "Access denied" when using HTTP authentication.

This could happen for several reasons:

  * $cfg['Servers'][$i]['controluser'] and/or $cfg['Servers'][$i]
    ['controlpass'] are wrong.
  * The username/password you specify in the login dialog are invalid.
  * You have already setup a security mechanism for the phpMyAdmin-directory,
    eg. a .htaccess file. This would interfere with phpMyAdmin's
    authentication, so remove it.

4.5 Is it possible to let users create their own databases?

Starting with 2.2.5, in the user management page, you can enter a wildcard
database name for a user (for example "joe%"), and put the privileges you want.
For example, adding SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER
would let a user create/manage his/her database(s).

4.6 How can I use the Host-based authentication additions?

If you have existing rules from an old .htaccess file, you can take them and
add a username between the 'deny'/'allow' and 'from' strings. Using the
username wildcard of '%' would be a major benefit here if your installation is
suited to using it. Then you can just add those updated lines into the $cfg
['Servers'][$i]['AllowDeny']['rules'] array.

If you want a pre-made sample, you can try this fragment. It stops the 'root'
user from logging in from any networks other than the private network IP
blocks.

//block root from logging in except from the private networks
$cfg['Servers'][$i]['AllowDeny']['order'] = 'deny,allow';
$cfg['Servers'][$i]['AllowDeny']['rules'] = array(
    'deny root from all',
    'allow root from localhost',
    'allow root from 10.0.0.0/8',
    'allow root from 192.168.0.0/16',
    'allow root from 172.16.0.0/12',
    );

4.7 Authentication window is displayed more than once, why?

This happens if you are using a URL to start phpMyAdmin which is different than
the one set in your $cfg['PmaAbsoluteUri']. For example, a missing "www", or
entering with an IP address while a domain name is defined in the config file.

4.8 Which parameters can I use in the URL that starts phpMyAdmin?

When starting phpMyAdmin, you can use the db, pma_username, pma_password and
server parameters. This last one can contain either the numeric host index
(from $i of the configuration file) or one of the host names present in the
configuration file. Using pma_username and pma_password has been tested along
with the usage of 'cookie' auth_type.

Browsers or client OS

5.1 I get an out of memory error, and my controls are non-functional, when
trying to create a table with more than 14 columns.

We could reproduce this problem only under Win98/98SE. Testing under WinNT4 or
Win2K, we could easily create more than 60 columns.
A workaround is to create a smaller number of columns, then come back to your
table properties and add the other columns.

5.2 With Xitami 2.5b4, phpMyAdmin won't process form fields.

This is not a phpMyAdmin problem but a Xitami known bug: you'll face it with
each script/website that use forms.
Upgrade or downgrade your Xitami server.

5.3 I have problems dumping tables with Konqueror (phpMyAdmin 2.2.2).

With Konqueror 2.1.1: plain dumps, zip and GZip dumps work ok, except that the
proposed file name for the dump is always 'tbl_dump.php'. Bzip2 dumps don't
seem to work.
With Konqueror 2.2.1: plain dumps work; zip dumps are placed into the user's
temporary directory, so they must be moved before closing Konqueror, or else
they disappear. GZip dumps give an error message.
Testing needs to be done for Konqueror 2.2.2.

5.4 I can't use the cookie authentication mode because Internet Explorer never
stores the cookies.

MS Internet Explorer seems to be really buggy about cookies, at least till
version 6.

5.5 In Internet Explorer 5.0, I get JavaScript errors when browsing my rows.

Upgrade to at least Internet Explorer 5.5 SP2.

5.6 In Internet Explorer 5.0, 5.5 or 6.0, I get an error (like "Page not
found") when trying to modify a row in a table with many columns, or with a
text column

Your table neither have a primary key nor an unique one, so we must use a long
URL to identify this row. There is a limit on the length of the URL in those
browsers, and this not happen in Netscape, for example. The workaround is to
create a primary or unique key, or use another browser.

5.7 I refresh (reload) my browser, and come back to the welcome page.

Some browsers support right-clicking into the frame you want to refresh, just
do this in the right frame.

5.8 With Mozilla 0.9.7 I have problems sending a query modified in the query
box.

Looks like a Mozilla bug: 0.9.6 was OK. We will keep an eye on future Mozilla
versions.

5.9 With Mozilla 0.9.? to 1.0 and Netscape 7.0-PR1 I can't type a whitespace in
the SQL-Query edit area: the page scrolls down.

This is a Mozilla bug (see bug #26882 at BugZilla).

5.10 With Netscape 4.75 I get empty rows between each row of data in a CSV
exported file.

This is a known Netscape 4.75 bug: it adds some line feeds when exporting data
in octet-stream mode. Since we can't detect the specific Netscape version, we
cannot workaround this bug.

5.11 Extended-ASCII characters like German umlauts are displayed wrong.

Please ensure that you have set your browser's character set to the one of the
language file you have selected on phpMyAdmin's start page. Alternatively, you
can try the auto detection mode that is supported by the recent versions of the
most browsers.

5.12 Mac OS X: Safari browser changes special characters to "?".

This issue has been reported by a OS X user, who adds that Chimera, Netscape
and Mozilla do not have this problem.

5.13 With Internet Explorer 5.5 or 6, and HTTP authentication type, I cannot
manage two servers: I log in to the first one, then the other one, but if I
switch back to the first, I have to log in on each operation.

This is a bug in Internet Explorer, other browsers do not behave this way.

5.14 Using Opera6, I can manage to get to the authentication, but nothing
happens after that, only a blank screen.

Please upgrade to Opera7 at least.

5.15 I have display problems with Safari.

Please upgrade to at least version 1.2.3.

5.16 With Internet Explorer, I get "Access is denied" Javascript errors. Or I
cannot make phpMyAdmin work under Windows.

Please check the following points:

  * Maybe you have defined your PmaAbsoluteUri setting in config.inc.php to an
    IP address and you are starting phpMyAdmin with a URL containing a domain
    name, or the reverse situation.
  * Security settings in IE and/or Microsoft Security Center are too high, thus
    blocking scripts execution.
  * The Windows Firewall is blocking Apache and MySQL. You must allow HTTP
    ports (80 or 443) and MySQL port (usually 3306) in the "in" and "out"
    directions.

5.17 With Firefox, I cannot delete rows of data or drop a database.

Many users have confirmed that the Tabbrowser Extensions plugin they installed
in their Firefox is causing the problem.

5.18 With Konqueror 4.2.x an invalid LIMIT clause is generated when I browse a
table.

This happens only when both of these conditions are met: using the http
authentication mode and register_globals being set to On on the server. It
seems to be a browser-specific problem; meanwhile use the cookie authentication
mode.

Using phpMyAdmin

6.1 I can't insert new rows into a table / I can't create a table - MySQL
brings up a SQL-error.

Examine the SQL error with care. Often the problem is caused by specifying a
wrong column-type.
Common errors include:

  * Using VARCHAR without a size argument
  * Using TEXT or BLOB with a size argument

Also, look at the syntax chapter in the MySQL manual to confirm that your
syntax is correct.

6.2 When I create a table, I set an index for two columns and phpMyAdmin
generates only one index with those two columns.

This is the way to create a multi-columns index. If you want two indexes,
create the first one when creating the table, save, then display the table
properties and click the Index link to create the other index.

6.3 How can I insert a null value into my table?

Since version 2.2.3, you have a checkbox for each column that can be null.
Before 2.2.3, you had to enter "null", without the quotes, as the column's
value. Since version 2.5.5, you have to use the checkbox to get a real NULL
value, so if you enter "NULL" this means you want a literal NULL in the column,
and not a NULL value (this works in PHP4).

6.4 How can I backup my database or table?

Click on a database or table name in the left frame, the properties will be
displayed. Then on the menu, click "Export", you can dump the structure, the
data, or both. This will generate standard SQL statements that can be used to
recreate your database/table.

You will need to choose "Save as file", so that phpMyAdmin can transmit the
resulting dump to your station. Depending on your PHP configuration, you will
see options to compress the dump. See also the $cfg['ExecTimeLimit']
configuration variable.

For additional help on this subject, look for the word "dump" in this document.

6.5 How can I restore (upload) my database or table using a dump? How can I run
a ".sql" file?

Click on a database name in the left frame, the properties will be displayed.
Select "Import" from the list of tabs in the right?hand frame (or "SQL" if your
phpMyAdmin version is previous to 2.7.0). In the "Location of the text file"
section, type in the path to your dump filename, or use the Browse button. Then
click Go.

With version 2.7.0, the import engine has been re?written, if possible it is
suggested that you upgrade to take advantage of the new features.

For additional help on this subject, look for the word "upload" in this
document.

6.6 How can I use the relation table in Query-by-example?

Here is an example with the tables persons, towns and countries, all located in
the database mydb. If you don't have a pma_relation table, create it as
explained in the configuration section. Then create the example tables:

CREATE TABLE REL_countries (
    country_code char(1) NOT NULL default '',
    description varchar(10) NOT NULL default '',
    PRIMARY KEY (country_code)
) TYPE=MyISAM;

INSERT INTO REL_countries VALUES ('C', 'Canada');

CREATE TABLE REL_persons (
    id tinyint(4) NOT NULL auto_increment,
    person_name varchar(32) NOT NULL default '',
    town_code varchar(5) default '0',
    country_code char(1) NOT NULL default '',
    PRIMARY KEY (id)
) TYPE=MyISAM;

INSERT INTO REL_persons VALUES (11, 'Marc', 'S', '');
INSERT INTO REL_persons VALUES (15, 'Paul', 'S', 'C');

CREATE TABLE REL_towns (
    town_code varchar(5) NOT NULL default '0',
    description varchar(30) NOT NULL default '',
    PRIMARY KEY (town_code)
) TYPE=MyISAM;

INSERT INTO REL_towns VALUES ('S', 'Sherbrooke');
INSERT INTO REL_towns VALUES ('M', 'Montr?al');

To setup appropriate links and display information:

  * on table "REL_persons" click Structure, then Relation view
  * in Links, for "town_code" choose "REL_towns->code"
  * in Links, for "country_code" choose "REL_countries->country_code"
  * on table "REL_towns" click Structure, then Relation view
  * in "Choose column to display", choose "description"
  * repeat the two previous steps for table "REL_countries"

Then test like this:

  * Click on your db name in the left frame
  * Choose "Query"
  * Use tables: persons, towns, countries
  * Click "Update query"
  * In the columns row, choose persons.person_name and click the "Show" tickbox
  * Do the same for towns.description and countries.descriptions in the other 2
    columns
  * Click "Update query" and you will see in the query box that the correct
    joins have been generated
  * Click "Submit query"

6.7 How can I use the "display column" feature?

Starting from the previous example, create the pma_table_info as explained in
the configuration section, then browse your persons table, and move the mouse
over a town code or country code.

See also FAQ 6.21 for an additional feature that "display column" enables:
drop-down list of possible values.

6.8 How can I produce a PDF schema of my database?

First the configuration variables "relation", "table_coords" and "pdf_pages"
have to be filled in.

Then you need to think about your schema layout. Which tables will go on which
pages?

  * Select your database in the left frame.
  * Choose "Operations" in the navigation bar at the top.
  * Choose "Edit PDF Pages" near the bottom of the page.
  * Enter a name for the first PDF page and click Go. If you like, you can use
    the "automatic layout," which will put all your linked tables onto the new
    page.
  * Select the name of the new page (making sure the Edit radio button is
    selected) and click Go.
  * Select a table from the list, enter its coordinates and click Save.
    Coordinates are relative; your diagram will be automatically scaled to fit
    the page. When initially placing tables on the page, just pick any
    coordinates -- say, 50x50. After clicking Save, you can then use the
    graphical editor to position the element correctly.
  * When you'd like to look at your PDF, first be sure to click the Save button
    beneath the list of tables and coordinates, to save any changes you made
    there. Then scroll all the way down, select the PDF options you want, and
    click Go.
  * Internet Explorer for Windows may suggest an incorrect filename when you
    try to save a generated PDF. When saving a generated PDF, be sure that the
    filename ends in ".pdf", for example "schema.pdf". Browsers on other
    operating systems, and other browsers on Windows, do not have this problem.

6.9 phpMyAdmin is changing the type of one of my columns!

No, it's MySQL that is doing silent column type changing.

6.10 When creating a privilege, what happens with underscores in the database
name?

If you do not put a backslash before the underscore, this is a wildcard grant,
and the underscore means "any character". So, if the database name is
"john_db", the user would get rights to john1db, john2db ...

If you put a backslash before the underscore, it means that the database name
will have a real underscore.

6.11 What is the curious symbol ? in the statistics pages?

It means "average".

6.12 I want to understand some Export options.

Structure:

  * "Add DROP TABLE" will add a line telling MySQL to drop the table, if it
    already exists during the import. It does NOT drop the table after your
    export, it only affects the import file.
  * "If Not Exists" will only create the table if it doesn't exist. Otherwise,
    you may get an error if the table name exists but has a different
    structure.
  * "Add AUTO_INCREMENT value" ensures that AUTO_INCREMENT value (if any) will
    be included in backup.
  * "Enclose table and column names with backquotes" ensures that column and
    table names formed with special characters are protected.
  * "Add into comments" includes column comments, relations, and MIME types set
    in the pmadb in the dump as SQL comments (/* xxx */).

Data:

  * "Complete inserts" adds the column names on every INSERT command, for
    better documentation (but resulting file is bigger).
  * "Extended inserts" provides a shorter dump file by using only once the
    INSERT verb and the table name.
  * "Delayed inserts" are best explained in the MySQL manual.
  * "Ignore inserts" treats errors as a warning instead. Again, more info is
    provided in the MySQL manual, but basically with this selected, invalid
    values are adjusted and inserted rather than causing the entire statement
    to fail.

6.13 I would like to create a database with a dot in its name.

This is a bad idea, because in MySQL the syntax "database.table" is the normal
way to reference a database and table name. Worse, MySQL will usually let you
create a database with a dot, but then you cannot work with it, nor delete it.

6.14 How do I set up the SQL Validator?

To use SQL Validator, you need PHP with XML, PCRE and PEAR support. In addition
you need a SOAP support, either as a PHP extension or as a PEAR SOAP module.

To install PEAR SOAP module, run "pear install Net_Socket Net_URL HTTP_Request
Mail_Mime Net_DIME SOAP" to get the necessary PEAR modules for usage.

If you use the Validator, you should be aware that any SQL statement you submit
will be stored anonymously (database/table/column names, strings, numbers
replaced with generic values). The Mimer SQL Validator itself, is ? 2001
Upright Database Technology. We utilize it as free SOAP service.

6.15 I want to add a BLOB column and put an index on it, but MySQL says "BLOB
column '...' used in key specification without a key length".

The right way to do this, is to create the column without any indexes, then
display the table structure and use the "Create an index" dialog. On this page,
you will be able to choose your BLOB column, and set a size to the index, which
is the condition to create an index on a BLOB column.

6.16 How can I simply move in page with plenty editing fields?

You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages with
many editing fields (table structure changes, row editing, etc.). You can also
have a look at the directive $cfg['DefaultPropDisplay'] ('vertical') and see if
this eases up editing for you.

6.17 Transformations: I can't enter my own mimetype! WTF is this feature then
useful for?

Slow down :). Defining mimetypes is of no use, if you can't put transformations
on them. Otherwise you could just put a comment on the column. Because entering
your own mimetype will cause serious syntax checking issues and validation,
this introduces a high-risk false-user-input situation. Instead you have to
initialize mimetypes using functions or empty mimetype definitions.
Plus, you have a whole overview of available mimetypes. Who knows all those
mimetypes by heart so he/she can enter it at will?

6.18 Bookmarks: Where can I store bookmarks? Why can't I see any bookmarks
below the query box? What is this variable for?

Any query you have executed can be stored as a bookmark on the page where the
results are displayed. You will find a button labeled 'Bookmark this query'
just at the end of the page.
As soon as you have stored a bookmark, it is related to the database you run
the query on. You can now access a bookmark dropdown on each page, the query
box appears on for that database.

Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
Just use the string /*[VARIABLE]*/ anywhere in your query. Everything which is
put into the value input box on the query box page will replace the string "/*
[VARIABLE]*/" in your stored query. Just be aware of that you HAVE to create a
valid query, otherwise your query won't be even able to be stored in the
database.
Also remember, that everything else inside the /*[VARIABLE]*/ string for your
query will remain the way it is, but will be stripped of the /**/ chars. So you
can use:

/*, [VARIABLE] AS myname */

which will be expanded to

, VARIABLE as myname

in your query, where VARIABLE is the string you entered in the input box. If an
empty string is provided, no replacements are made.

A more complex example. Say you have stored this query:

SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE]%' */

Say, you now enter "phpMyAdmin" as the variable for the stored query, the full
query will be:

SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'

You can use multiple occurrences of /*[VARIABLE]*/ in a single query (that is,
multiple occurrences of the same variable).
NOTE THE ABSENCE OF SPACES inside the "/**/" construct. Any spaces inserted
there will be later also inserted as spaces in your query and may lead to
unexpected results especially when using the variable expansion inside of a
"LIKE ''" expression.
Your initial query which is going to be stored as a bookmark has to yield at
least one result row so you can store the bookmark. You may have that to work
around using well positioned "/**/" comments.

6.19 How can I create simple L^AT[E]X document to include exported table?

You can simply include table in your L^AT[E]X documents, minimal sample
document should look like following one (assuming you have table exported in
file table.tex):

\documentclass{article} % or any class you want
\usepackage{longtable}  % for displaying table
\begin{document}        % start of document
\include{table}         % including exported table
\end{document}          % end of document

6.20 I see a lot of databases which are not mine, and cannot access them.

You have one of these global privileges: CREATE TEMPORARY TABLES, SHOW
DATABASES, LOCK TABLES. Those privileges also enable users to see all the
database names. See this bug report.

So if your users do not need those privileges, you can remove them and their
databases list will shorten.

6.21 In edit/insert mode, how can I see a list of possible values for a column,
based on some foreign table?

You have to setup appropriate links between the tables, and also setup the
"display column" in the foreign table. See FAQ 6.6 for an example. Then, if
there are 100 values or less in the foreign table, a drop-down list of values
will be available. You will see two lists of values, the first list containing
the key and the display column, the second list containing the display column
and the key. The reason for this is to be able to type the first letter of
either the key or the display column.

For 100 values or more, a distinct window will appear, to browse foreign key
values and choose one. To change the default limit of 100, see $cfg
['ForeignKeyMaxLimit'].

6.22 Bookmarks: Can I execute a default bookmark automatically when entering
Browse mode for a table?

Yes. If a bookmark has the same label as a table name, it will be executed.

6.23 Export: I heard phpMyAdmin can export Microsoft Excel files, how can I
enable that?

You can use CSV for Microsoft Excel, which works out of the box, but phpMyAdmin
supports direct export to Microsoft Excel version 97 and newer. For this to
work, you need to set $cfg['TempDir'] to a place where the web server user can
write (for example './tmp').

To create the temporary directory on a UNIX-based system, you can do:

cd phpMyAdmin
mkdir tmp
chmod o+rwx tmp

6.24 Now that phpMyAdmin supports native MySQL 4.1.x column comments, what
happens to my column comments stored in pmadb?

Automatic migration of a table's pmadb-style column comments to the native ones
is done whenever you enter Structure page for this table.

6.25 How does BLOB streaming work in phpMyAdmin?

For general information about BLOB streaming on MySQL, visit blobstreaming.org.
You need the following components:

  * PBMS BLOB Streaming Daemon for MySQL (0.5.15 or later)
  * Streaming enabled PBXT Storage engine for MySQL (1.0.11-6 or later)
  * PBMS Client Library for MySQL (0.5.15 or later)
  * PBMS PHP Extension for MySQL (0.1.1 or later)

Here are details about configuration and operation:

 1. In config.inc.php your host should be defined with a FQDN (fully qualified
    domain name) instead of "localhost".
 2. Ensure that your target table is under the PBXT storage engine and has a
    LONGBLOB column (which must be nullable if you want to remove the BLOB
    reference from it).
 3. When you insert or update a row in this table, put a checkmark on the
    "Upload to BLOB repository" optional choice; otherwise, the upload will be
    done directly in your LONGBLOB column instead of the repository.
 4. Finally when you browse your table, you'll see in your column a link to
    stream your data, for example "View image". A header containing the correct
    MIME-type will be sent to your browser; this MIME-type was stored at upload
    time.

6.26 How can I select a range of rows?

Click the first row of the range, hold the shift key and click the last row of
the range. This works everywhere you see rows, for example in Browse mode or on
the Structure page.

6.27 What format strings can I use?

In all places where phpMyAdmin accepts format strings, you can use @VARIABLE@
expansion and strftime format strings. The expanded variables depend on a
context (for example, if you haven't chosen a table, you can not get the table
name), but the following variables can be used:

@HTTP_HOST@
    HTTP host that runs phpMyAdmin
@SERVER@
    MySQL server name
@VERBOSE@
    Verbose MySQL server name as defined in server configuration
@VSERVER@
    Verbose MySQL server name if set, otherwise normal
@DATABASE@
    Currently opened database
@TABLE@
    Currently opened table
@FIELDS@
    Fields of currently opened table
@PHPMYADMIN@
    phpMyAdmin with version

6.28 How can I easily edit relational schema for export?

By clicking on the button 'toggle scratchboard' on the page where you edit x/y
coordinates of those elements you can activate a scratchboard where all your
elements are placed. By clicking on an element, you can move them around in the
pre-defined area and the x/y coordinates will get updated dynamically.
Likewise, when entering a new position directly into the input field, the new
position in the scratchboard changes after your cursor leaves the input field.

You have to click on the 'OK'-button below the tables to save the new
positions. If you want to place a new element, first add it to the table of
elements and then you can drag the new element around.

By changing the paper size and the orientation you can change the size of the
scratchboard as well. You can do so by just changing the dropdown field below,
and the scratchboard will resize automatically, without interfering with the
current placement of the elements.

If ever an element gets out of range you can either enlarge the paper size or
click on the 'reset' button to place all elements below each other.

6.29 Why can't I get a chart from my query result table?

Not every table can be put to the chart. Only tables with one, two or three
columns can be visualised as a chart. Moreover the table must be in a special
format for chart script to understand it. Currently supported formats can be
found in the wiki.

phpMyAdmin project

7.1 I have found a bug. How do I inform developers?

Our Bug Tracker is located at http://sf.net/projects/phpmyadmin/ under the Bugs
section.

But please first discuss your bug with other users:
https://sourceforge.net/projects/phpmyadmin/forums.

7.2 I want to translate the messages to a new language or upgrade an existing
language, where do I start?

Always use latest Git version of the po file to translate. You can optionally
translate online at our translation server where you can also get the latest po
files and merge them with your translations. For creating a new translation
simply use po/phpmyadmin.pot and generate po/LANG_CODE.po for your language
(you can use msginit -i po/phpmyadmin.pot -l LANG_CODE --no-translator -o po/
LANG_CODE.po to do this) or ask on the mailing list to add the translation to
the web interface. More details are available on our wiki.

Please note that we try not to use HTML entities like &eacute; in the
translations, since we define the right character set in the file. With HTML
entities, the text on JavaScript messages would not display correctly. However
there are some entities that need to be there: quotes, non-breakable spaces,
ampersands, less than, greater than.

You can then put your translations, as a zip file to avoid losing special
characters, on the sourceforge.net translation tracker.

It would be a good idea to subscribe to the phpmyadmin-translators mailing
list, because this is where we ask for translations of new messages.

Documentation is being translated using po4a and gettext (see documentation for
existing translations). To start, checkout localized_docs/po from Git, or just
go to the translation server and translate it online. If your language is
missing, just contact Michal ?iha?; he will add it. If you prefer to directly
translate the po files, please put updated ones into our translation tracker.

7.3 I would like to help out with the development of phpMyAdmin. How should I
proceed?

The following method is preferred for new developers:

 1. fetch the current git repository over anonymous git:
    git clone git://phpmyadmin.git.sourceforge.net/gitroot/phpmyadmin/
    phpmyadmin
 2. add your stuff
 3. generate patch with your changes: git diff > xxx.diff
 4. submit your patch via the patch tracker of the phpMyAdmin project.

More details on git are available on our wiki.

Write access to the repository is granted only to experienced developers who
have already contributed something useful to phpMyAdmin.
Also, have a look at the Developers section.

Security

8.1 Where can I get information about the security alerts issued for
phpMyAdmin?

Please refer to http://www.phpmyadmin.net/home_page/security.php

8.2 How can I protect phpMyAdmin against brute force attacks?

If you use Apache web server, phpMyAdmin exports information about
authentication to the Apache environment and it can be used in Apache logs.
Currently there are two variables available:

userID
    User name of currently active user (he does not have to be logged in).
userStatus
    Status of currently active user, one of ok (user is logged in),
    mysql-denied (MySQL denied user login), allow-denied (user denied by allow/
    deny rules), root-denied (root is denied in configuration), empty-denied
    (empty password is denied).

LogFormat directive for Apache can look like following:

LogFormat "%h %l %u %t \"%r\" %>s %b \
\"%{Referer}i\" \"%{User-Agent}i\" %{userID}n %{userStatus}n"   pma_combined

You can then use any log analyzing tools to detect possible break-in attempts.

Synchronization

9.1 How can I synchronize two databases/tables in phpMyAdmin?

You can now synchronize databases/tables in phpMyAdmin using the Synchronize
feature. It allows you to connect to local as well as remote servers. This
requires you to enter server host name, username, password, port and the name
of the database. Therefore you can now synchronize your databases placed on the
same server or some remote server.

This feature is helpful for developers who need to replicate their database?s
structure as well as data. Moreover, this feature not only helps replication
but also facilitates the user to keep his/her database in sync with another
database. Other than the full database, certain tables of the databases can
also be synchronized.

You need to fill in the host name of the server, the username and password of
an user account already there in MySQL. Port is by default populated with 3306
(MySQL default port). Then the name of the database should be mentioned at the
end. All the information other than the port needs to be filled explicitly for
the source as well as target servers.

After successfully passing through the authentication phase, the source and
target database table names will be displayed. It will be a tabular
representation.

On the left, are listed the source database table names. Some of the names have
a + plus sign preceding them. This shows that these tables are only present in
source database and they need to be added to the target database in order to
synchronize the target database. The tables whose names are not preceded by a +
sign are already present in the target database.

On the right, are listed the target database table names. There are few table
names that have (not present) appended after their names. This means that these
tables are to be created in target database in order to synchronize target
database with source database. Some table names have a - minus sign preceding
them. This shows that these tables are only present in target database and they
will remain unchanged in the target database. The column in the middle shows
the difference between the source and target corresponding tables.

The difference is depicted by the red and green buttons with S and D letters,
indicating that either Structure or Data are not up to date. By clicking on
them, they will turn grey, what means that they will be synchronized.

Developers Information

phpMyAdmin is Open Source, so you're invited to contribute to it. Many great
features have been written by other people and you too can help to make
phpMyAdmin a useful tool.

If you're planning to contribute source, please read the following information:

  * All files include libraries/header.inc.php (layout),. libraries/
    common.lib.php (common functions) and config.inc.php.
    Only configuration data should go in config.inc.php. Please keep it free
    from other code.
    Commonly used functions should be added to libraries/common.lib.php and
    more specific ones may be added within a library stored into the libraries
    sub-directory.
  * Obviously, you're free to use whatever coding style you want. But please
    try to keep your code as simple as possible: beginners are using phpMyAdmin
    as an example application.
    As far as possible, we want the scripts to be XHTML1.0 and CSS2 compliant
    on one hand, they fit the PEAR coding standards on the other hand. Please
    pay attention to this.
  * Please enable showing PHP errors and warnings by the $cfg['Error_Handler']
    ['display'] configuration directive.
  * Please try to keep up the file-naming conventions. Table-related stuff goes
    to tbl_*.php, db-related code to db_*.php, server-related tools to
    server_*.php and so on.
  * Please use gettext wrappers around all messages (__('Some text') or
    _ngettext() function). To translate them, you need to call scripts/
    update-po script. To use translated messages, call scripts/generate-mo,
    which generates binary files read by Gettext.
  * If you want to be really helpful, write an entry for the ChangeLog.
  * The DBG extension (PHP Debugger DBG) is now supported by phpMyAdmin for
    developers to better debug and profile their code.
    Please see the $cfg['DBG']* configuration options for more information.
    This is in memoriam of the Space Shuttle Columbia (STS-107) which was lost
    during its re-entry into Earth's atmosphere and in memory of the brave men
    and women who gave their lives for the people of Earth.

This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea to
create a web-based interface to MySQL using PHP3. Although I have not used any
of his source-code, there are some concepts I've borrowed from him. phpMyAdmin
was created because Peter told me he wasn't going to further develop his
(great) tool.

Thanks go to

  * Amalesh Kempf <ak-lsml_at_living-source.com> who contributed the code for
    the check when dropping a table or database. He also suggested that you
    should be able to specify the primary key on tbl_create.php3. To version
    1.1.1 he contributed the ldi_*.php3-set (Import text-files) as well as a
    bug-report. Plus many smaller improvements.
  * Jan Legenhausen <jan_at_nrw.net>: He made many of the changes that were
    introduced in 1.3.0 (including quite significant ones like the
    authentication). For 1.4.1 he enhanced the table-dump feature. Plus
    bug-fixes and help.
  * Marc Delisle <DelislMa_at_CollegeSherbrooke.qc.ca> made phpMyAdmin
    language-independent by outsourcing the strings to a separate file. He also
    contributed the French translation.
  * Alexandr Bravo <abravo_at_hq.admiral.ru> who contributed tbl_select.php3, a
    feature to display only some columns from a table.
  * Chris Jackson <chrisj_at_ctel.net> added support for MySQL functions in
    tbl_change.php3. He also added the "Query by Example" feature in 2.0.
  * Dave Walton <walton_at_nordicdms.com> added support for multiple servers
    and is a regular contributor for bug-fixes.
  * Gabriel Ash <ga244_at_is8.nyu.edu> contributed the random access features
    for 2.0.6.

The following people have contributed minor changes, enhancements, bugfixes or
support for a new language:

Jim Kraai, Jordi Bruguera, Miquel Obrador, Geert Lund, Thomas Kleemann,
Alexander Leidinger, Kiko Albiol, Daniel C. Chao, Pavel Piankov, Sascha
Kettler, Joe Pruett, Renato Lins, Mark Kronsbein, Jannis Hermanns, G. Wieggers.

And thanks to everyone else who sent me email with suggestions, bug-reports and
or just some feedback.
