Configuration

Almost all configurable data is placed in config.inc.php. If this file does not exist, please refer to the Installation 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.

If a directive is missing from your file, you can just add another line with the file. This file is for over-writing the defaults; if you wish to use the default value there’s no need to add a line here.

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.

Note

Some distributions (eg. Debian or Ubuntu) store config.inc.php in /etc/phpmyadmin instead of within phpMyAdmin sources.

Warning

Mac users should note that if you are on a version before Mac OS X, 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.

Basic settings

$cfg['PmaAbsoluteUri']
Type:string
Default value:''

Deprecated since version 4.6.0: This setting is no longer available since phpMyAdmin 4.6.0. Please adjust your webserver instead.

Sets here the complete URL (with full path) to your phpMyAdmin installation’s directory. E.g. http://www.example.net/path_to_your_phpMyAdmin_directory/. Note also that the URL on most of 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 $cfg['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']
Type:boolean
Default value:false

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']
Type:boolean
Default value:false

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['LoginCookieValidityDisableWarning']
Type:boolean
Default value:false

A warning is displayed on the main page if the PHP parameter session.gc_maxlifetime is lower than cookie validity configured in phpMyAdmin.

You can set this parameter to true to stop this message from appearing.

$cfg['ServerLibraryDifference_DisableWarning']
Type:boolean
Default value:false

A warning is displayed on the main page if there is a difference between the MySQL library and server version.

You can set this parameter to true to stop this message from appearing.

$cfg['ReservedWordDisableWarning']
Type:boolean
Default value:false

This warning is displayed on the Structure page of a table if one or more column names match with words which are MySQL reserved.

If you want to turn off this warning, you can set it to true and warning will no longer be displayed.

$cfg['TranslationWarningThreshold']
Type:integer
Default value:80

Show warning about incomplete translations on certain threshold.

$cfg['SendErrorReports']
Type:string
Default value:'ask'

Sets the default behavior for JavaScript error reporting.

Whenever an error is detected in the JavaScript execution, an error report may be sent to the phpMyAdmin team if the user agrees.

The default setting of 'ask' will ask the user everytime there is a new error report. However you can set this parameter to 'always' to send error reports without asking for confirmation or you can set it to 'never' to never send error reports.

This directive is available both in the configuration file and in users preferences. If the person in charge of a multi-user installation prefers to disable this feature for all users, a value of 'never' should be set, and the $cfg['UserprefsDisallow'] directive should contain 'SendErrorReports' in one of its array values.

$cfg['ConsoleEnterExecutes']
Type:boolean
Default value:false

Setting this to true allows the user to execute queries by pressing Enter instead of Ctrl+Enter. A new line can be inserted by pressing Shift + Enter.

The behaviour of the console can be temporarily changed using console’s settings interface.

$cfg['AllowThirdPartyFraming']
Type:boolean
Default value:false

Setting this to true allows phpMyAdmin to be included inside a frame, and is a potential security hole allowing cross-frame scripting attacks or clickjacking.

Server connection settings

$cfg['Servers']
Type:array
Default value:one server array with settings listed below

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).

Note

The $cfg['Servers'] array starts with $cfg[‘Servers’][1]. Do not use $cfg[‘Servers’][0]. If you want more than one server, just copy following section (including $i incrementation) serveral times. There is no need to define full server array, just define values you need to change.

$cfg['Servers'][$i]['host']
Type:string
Default value:'localhost'

The hostname or IP address of your $i-th MySQL-server. E.g. localhost.

Possible values are:

  • hostname, e.g., 'localhost' or 'mydb.example.org'
  • IP address, e.g., '127.0.0.1' or '192.168.10.1'
  • dot - '.', i.e., use named pipes on windows systems
  • empty - '', disables this server

Note

phpMyAdmin supports connecting to MySQL servers reachable via IPv6 only.
To connect to an IPv6 MySQL server, enter its IPv6 address in this field.
$cfg['Servers'][$i]['port']
Type:string
Default value:''

The port-number of your $i-th MySQL-server. Default is 3306 (leave blank).

Note

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']
Type:string
Default value:''

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']
Type:boolean
Default value:false

Whether to enable SSL for the connection between phpMyAdmin and the MySQL server.

When using the 'mysql' extension, none of the remaining 'ssl...' configuration options apply.

We strongly recommend the 'mysqli' extension when using this option.

$cfg['Servers'][$i]['ssl_key']
Type:string
Default value:NULL

Path to the key file when using SSL for connecting to the MySQL server.

For example:

$cfg['Servers'][$i]['ssl_key'] = '/etc/mysql/server-key.pem';
$cfg['Servers'][$i]['ssl_cert']
Type:string
Default value:NULL

Path to the cert file when using SSL for connecting to the MySQL server.

$cfg['Servers'][$i]['ssl_ca']
Type:string
Default value:NULL

Path to the CA file when using SSL for connecting to the MySQL server.

$cfg['Servers'][$i]['ssl_ca_path']
Type:string
Default value:NULL

Directory containing trusted SSL CA certificates in PEM format.

$cfg['Servers'][$i]['ssl_ciphers']
Type:string
Default value:NULL

List of allowable ciphers for SSL connections to the MySQL server.

$cfg['Servers'][$i]['ssl_verify']
Type:boolean
Default value:true

If your PHP install uses the MySQL Native Driver (mysqlnd), your MySQL server is 5.6 or later, and your SSL certificate is self-signed, there is a chance your SSL connection will fail due to validation. Setting this to false will disable the validation check.

Note

This flag only works with PHP 5.6.16 or later

$cfg['Servers'][$i]['connect_type']
Type:string
Default value:'tcp'

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]['compress']
Type:boolean
Default value:false

Whether to use a compressed protocol for the MySQL server connection or not (experimental).

$cfg['Servers'][$i]['controlhost']
Type:string
Default value:''

Permits to use an alternate host to hold the configuration storage data.

$cfg['Servers'][$i]['controlport']
Type:string
Default value:''

Permits to use an alternate port to connect to the host that holds the configuration storage.

$cfg['Servers'][$i]['controluser']
Type:string
Default value:''
$cfg['Servers'][$i]['controlpass']
Type:string
Default value:''

This special account is used for 2 distinct purposes: to make possible all relational features (see $cfg['Servers'][$i]['pmadb']).

Changed in version 2.2.5: those were called stduser and stdpass

Installation, Using authentication modes, phpMyAdmin configuration storage

$cfg['Servers'][$i]['auth_type']
Type:string
Default value:'cookie'

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') allows you to log in as any valid MySQL user with the help of cookies.
  • ‘http’ authentication allows you to log in as any valid MySQL user via HTTP-Auth.
  • ‘signon’ authentication mode ($auth_type = 'signon') allows you to log in from prepared PHP session data or using supplied PHP script.

Using authentication modes

$cfg['Servers'][$i]['auth_http_realm']
Type:string
Default value:''

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']
Type:string
Default value:''

The name of the file containing Swekey authentication mode ids and login names for hardware authentication. Leave empty to deactivate this feature.

$cfg['Servers'][$i]['user']
Type:string
Default value:'root'
$cfg['Servers'][$i]['password']
Type:string
Default value:''

When using $cfg['Servers'][$i]['auth_type'] set to ‘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']
Type:boolean
Default value:false

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']
Type:string or array
Default value:''

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');

Changed in version 4.0.0: Previous versions permitted to specify the display order of the database names via this directive.

$cfg['Servers'][$i]['hide_db']
Type:string
Default value:''

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']
Type:string
Default value:''

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']
Type:string
Default value:''

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']
Type:string or false
Default value:''

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:

This feature can be disabled by setting the configuration to false.

$cfg['Servers'][$i]['relation']
Type:string or false
Default value:''

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:

The keys can be numeric or character.

To allow the usage of this functionality:

  • set up $cfg['Servers'][$i]['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.

This feature can be disabled by setting the configuration to false.

Note

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']
Type:string or false
Default value:''

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:

This feature can be disabled by setting the configuration to false.

6.7 How can I use the “display column” feature?

$cfg['Servers'][$i]['table_coords']
Type:string or false
Default value:''
$cfg['Servers'][$i]['pdf_pages']
Type:string or false
Default value:''

Since release 2.3.0 you can have phpMyAdmin create PDF pages showing the relations between your tables. Further, the designer interface permits visually managing the relations. 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:

This feature can be disabled by setting either of the configurations to false.

See also

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

$cfg['Servers'][$i]['column_info']
Type:string or false
Default value:''

This part requires a content update! 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’.

Starting with release 4.3.0, a new input-oriented transformation system has been introduced. Also, backward compatibility code used in the old transformations system was removed. As a result, an update to column_info table is necessary for previous transformations and the new input-oriented transformation system to work. phpMyAdmin will upgrade it automatically for you by analyzing your current column_info table structure. However, if something goes wrong with the auto-upgrade then you can use the SQL script found in ./sql/upgrade_column_info_4_3_0+.sql to upgrade it manually.

To allow the usage of this functionality:

  • set up $cfg['Servers'][$i]['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: and remember that the Variable in config.inc.php has been renamed from $cfg['Servers'][$i]['column_comments'] to $cfg['Servers'][$i]['column_info']

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

  • to update your PRE-4.3.0 Column_info table manually use this ./sql/upgrade_column_info_4_3_0+.sql SQL script.

This feature can be disabled by setting the configuration to false.

Note

For auto-upgrade functionality to work, your $cfg['Servers'][$i]['controluser'] must have ALTER privilege on phpmyadmin database. See the MySQL documentation for GRANT on how to GRANT privileges to a user.

$cfg['Servers'][$i]['history']
Type:string or false
Default value:''

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:

This feature can be disabled by setting the configuration to false.

$cfg['Servers'][$i]['recent']
Type:string or false
Default value:''

Since release 3.5.0 you can show recently used tables in the navigation panel. It helps you to jump across table directly, without the need to select the database, and then select the table. Using $cfg['NumRecentTables'] you can configure the maximum number of recent tables shown. When you select a table from the list, it will jump to the page specified in $cfg['NavigationTreeDefaultTabTable'].

Without configuring the storage, you can still access the recently used tables, but it will disappear after you logout.

To allow the usage of this functionality persistently:

This feature can be disabled by setting the configuration to false.

$cfg['Servers'][$i]['favorite']
Type:string or false
Default value:''

Since release 4.2.0 you can show a list of selected tables in the navigation panel. It helps you to jump to the table directly, without the need to select the database, and then select the table. When you select a table from the list, it will jump to the page specified in $cfg['NavigationTreeDefaultTabTable'].

You can add tables to this list or remove tables from it in database structure page by clicking on the star icons next to table names. Using $cfg['NumFavoriteTables'] you can configure the maximum number of favorite tables shown.

Without configuring the storage, you can still access the favorite tables, but it will disappear after you logout.

To allow the usage of this functionality persistently:

This feature can be disabled by setting the configuration to false.

$cfg['Servers'][$i]['table_uiprefs']
Type:string or false
Default value:''

Since release 3.5.0 phpMyAdmin can be configured to remember several things (sorted column $cfg['RememberSorting'], column order, and column visibility from a database table) for browsing tables. Without configuring the storage, these features still can be used, but the values will disappear after you logout.

To allow the usage of these functionality persistently:

This feature can be disabled by setting the configuration to false.

$cfg['Servers'][$i]['users']
Type:string or false
Default value:''
$cfg['Servers'][$i]['usergroups']
Type:string or false
Default value:''

Since release 4.1.0 you can create different user groups with menu items attached to them. Users can be assigned to these groups and the logged in user would only see menu items configured to the usergroup he is assigned to. To do this it needs two tables “usergroups” (storing allowed menu items for each user group) and “users” (storing users and their assignments to user groups).

To allow the usage of this functionality:

This feature can be disabled by setting either of the configurations to false.

$cfg['Servers'][$i]['navigationhiding']
Type:string or false
Default value:''

Since release 4.1.0 you can hide/show items in the navigation tree.

To allow the usage of this functionality:

This feature can be disabled by setting the configuration to false.

$cfg['Servers'][$i]['central_columns']
Type:string or false
Default value:''

Since release 4.3.0 you can have a central list of columns per database. You can add/remove columns to the list as per your requirement. These columns in the central list will be available to use while you create a new column for a table or create a table itself. You can select a column from central list while creating a new column, it will save you from writing the same column definition over again or from writing different names for similar column.

To allow the usage of this functionality:

This feature can be disabled by setting the configuration to false.

$cfg['Servers'][$i]['designer_settings']
Type:string or false
Default value:''

Since release 4.5.0 your designer settings can be remembered. Your choice regarding ‘Angular/Direct Links’, ‘Snap to Grid’, ‘Toggle Relation Lines’, ‘Small/Big All’, ‘Move Menu’ and ‘Pin Text’ can be remembered persistently.

To allow the usage of this functionality:

This feature can be disabled by setting the configuration to false.

$cfg['Servers'][$i]['savedsearches']
Type:string or false
Default value:''

Since release 4.2.0 you can save and load query-by-example searches from the Database > Query panel.

To allow the usage of this functionality:

This feature can be disabled by setting the configuration to false.

$cfg['Servers'][$i]['export_templates']
Type:string or false
Default value:''

Since release 4.5.0 you can save and load export templates.

To allow the usage of this functionality:

This feature can be disabled by setting the configuration to false.

$cfg['Servers'][$i]['tracking']
Type:string or false
Default value:''

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:

This feature can be disabled by setting the configuration to false.

$cfg['Servers'][$i]['tracking_version_auto_create']
Type:boolean
Default value:false

Whether the tracking mechanism creates versions for tables and views automatically.

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']
Type:string
Default value:'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'

Defines the list of statements the auto-creation uses for new versions.

$cfg['Servers'][$i]['tracking_add_drop_view']
Type:boolean
Default value:true

Whether a DROP VIEW IF EXISTS statement will be added as first line to the log when creating a view.

$cfg['Servers'][$i]['tracking_add_drop_table']
Type:boolean
Default value:true

Whether a DROP TABLE IF EXISTS statement will be added as first line to the log when creating a table.

$cfg['Servers'][$i]['tracking_add_drop_database']
Type:boolean
Default value:true

Whether a DROP DATABASE IF EXISTS statement will be added as first line to the log when creating a database.

$cfg['Servers'][$i]['userconfig']
Type:string or false
Default value:''

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 $cfg['Servers'][$i]['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:

This feature can be disabled by setting the configuration to false.

$cfg['Servers'][$i]['MaxTableUiprefs']
Type:integer
Default value:100

Maximum number of rows saved in $cfg['Servers'][$i]['table_uiprefs'] table.

When tables are dropped or renamed, $cfg['Servers'][$i]['table_uiprefs'] may contain invalid data (referring to tables which no longer exist). We only keep this number of newest rows in $cfg['Servers'][$i]['table_uiprefs'] and automatically delete older rows.

$cfg['Servers'][$i]['SessionTimeZone']
Type:string
Default value:''

Sets the time zone used by phpMyAdmin. Leave blank to use the time zone of your database server. Possible values are explained at http://dev.mysql.com/doc/refman/5.7/en/time-zone-support.html

This is useful when your database server uses a time zone which is different from the time zone you want to use in phpMyAdmin.

$cfg['Servers'][$i]['AllowRoot']
Type:boolean
Default value:true

Whether to allow root access. This is just a shortcut for the $cfg['Servers'][$i]['AllowDeny']['rules'] below.

$cfg['Servers'][$i]['AllowNoPassword']
Type:boolean
Default value:false

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']
Type:string
Default value:''

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']
Type:array of strings
Default value:array()

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 address 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)

For IPv6 addresses, the following work:

  • xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx (an exact IPv6 address)
  • xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:[yyyy-zzzz] (an IPv6 address range)
  • xxxx:xxxx:xxxx:xxxx/nn (CIDR, Classless Inter-Domain Routing type IPv6 addresses)

But the following does not work:

  • xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xx[yyy-zzz] (partial IPv6 address range)
$cfg['Servers'][$i]['DisableIS']
Type:boolean
Default value:false

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]['SignonScript']
Type:string
Default value:''

Name of PHP script to be sourced and executed to obtain login credentials. This is alternative approach to session based single signon. The script has to provide a function called get_login_credentials which returns list of username and password, accepting single parameter of existing username (can be empty). See examples/signon-script.php for an example:

<?php
/* vim: set expandtab sw=4 ts=4 sts=4: */
/**
 * Single signon for phpMyAdmin
 *
 * This is just example how to use script based single signon with
 * phpMyAdmin, it is not intended to be perfect code and look, only
 * shows how you can integrate this functionality in your application.
 *
 * @package    PhpMyAdmin
 * @subpackage Example
 */


/**
 * This function returns username and password.
 *
 * It can optionally use configured username as parameter.
 *
 * @param string $user User name
 *
 * @return array
 */
function get_login_credentials($user)
{
    /* Optionally we can use passed username */
    if (!empty($user)) {
        return array($user, 'password');
    }

    /* Here we would retrieve the credentials */
    $credentials = array('root', '');

    return $credentials;
}

Signon authentication mode

$cfg['Servers'][$i]['SignonSession']
Type:string
Default value:''

Name of session which will be used for signon authentication method. You should use something different than phpMyAdmin, because this is session which phpMyAdmin uses internally. Takes effect only if $cfg['Servers'][$i]['SignonScript'] is not configured.

See also

Signon authentication mode

$cfg['Servers'][$i]['SignonURL']
Type:string
Default value:''

URL where user will be redirected to log in for signon authentication method. Should be absolute including protocol.

Signon authentication mode

$cfg['Servers'][$i]['LogoutURL']
Type:string
Default value:''

URL where user will be redirected after logout (doesn’t affect config authentication method). Should be absolute including protocol.

Generic settings

$cfg['ServerDefault']
Type:integer
Default value:1

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['VersionCheck']

Note

This setting can be adjusted by your vendor.

$cfg['ProxyUrl']

You need this if the server where phpMyAdmin is installed does not have direct access to the internet. The format is: “hostname:portnumber”

$cfg['ProxyUser']
Type:string
Default value:“”

The username for authenticating with the proxy. By default, no authentication is performed. If a username is supplied, Basic Authentication will be performed. No other types of authentication are currently supported.

$cfg['ProxyPass']
Type:string
Default value:“”

The password for authenticating with the proxy.

$cfg['MaxDbList']

Default value:true

Whether or not to show hints (for example, hints when hovering over table headers).

$cfg['MaxCharactersInDisplayedSQL']
Type:integer
Default value:1000

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['PersistentConnections']
Type:boolean
Default value:false

Whether persistent connections should be used or not. Works with following extensions:

$cfg['ForceSSL']
Type:boolean
Default value:false

Deprecated since version 4.6.0: This setting is no longer available since phpMyAdmin 4.6.0. Please adjust your webserver instead.

Whether to force using https while accessing phpMyAdmin. In a reverse proxy setup, setting this to true is not supported.

Note

In some setups (like separate SSL proxy or load balancer) you might have to set $cfg['PmaAbsoluteUri'] for correct redirection.

$cfg['ExecTimeLimit']
Type:integer [number of seconds]
Default value:300

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 but has no effect when PHP is running in safe mode.

$cfg['SessionSavePath']
Type:string
Default value:''

Path for storing session data (session_save_path PHP parameter).

$cfg['MemoryLimit']
Type:string [number of bytes]
Default value:'-1'

Set the number of bytes a script is allowed to allocate. If set to '-1', no limit is imposed. If set to '0', no change of the memory limit is attempted and the php.ini memory_limit is used.

This setting is used while importing/exporting dump files 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']
Type:boolean
Default value:false

Mark used tables and make it possible to show databases with locked tables (since MySQL 3.23.30).

$cfg['DefaultForeignKeyChecks']
Type:string
Default value:'default'

Default value of the checkbox for foreign key checks, to disable/enable foreign key checks for certain queries. The possible values are 'default', 'enable' or 'disable'. If set to 'default', the value of the MySQL variable FOREIGN_KEY_CHECKS is used.

$cfg['AllowUserDropDatabase']
Type:boolean
Default value:false

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.

Note

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']
Type:boolean
Default value:true

Whether a warning (“Are your really sure...”) should be displayed when you’re about to lose data.

$cfg['UseDbSearch']
Type:boolean
Default value:true

Define whether the “search string inside database” is enabled or not.

$cfg['ShowCreateDb']
Type:boolean
Default value:true

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['ShowGitRevision']
Type:boolean
Default value:true

Defines whether to display informations about the current Git revision (if applicable) on the main panel.

$cfg['MysqlMinVersion']
Type:array

Defines the minimum supported MySQL version. The default is chosen by the phpMyAdmin team; however this directive was asked by a developer of the Plesk control panel to ease integration with older MySQL servers (where most of the phpMyAdmin features work).

$cfg['RowActionType']
Type:string
Default value:'both'

Whether to display icons or text or both icons and text in table row action segment. Value can be either of 'icons', 'text' or 'both'.

$cfg['ShowAll']
Type:boolean
Default value:false

Defines whether a user should be displayed a “Show all” button in browse mode or not in all cases. By default it is shown only on small tables (less than 500 rows) to avoid performance issues while getting too many rows.

$cfg['MaxRows']
Type:integer
Default value:25

Number of rows displayed when browsing a result set and no LIMIT clause is used. If the result set contains more rows, “Previous” and “Next” links will be shown. Possible values: 25,50,100,250,500.

  • 'all' to disallow editing of all BINARY or BLOB columns.
$cfg['ShowFunctionFields']
Type:boolean

Defines whether to allow the use of zip/GZip/BZip2 compression when creating a dump file

$cfg['CompressOnFly']
Type:boolean
Default value:true

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['Export']
Type:array
Default value: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']
Type:string
Default value:'quick'

Default value:''

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']
Type:string
Default value:'auto'

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
  • mb - use mbstring extension
  • none - disable encoding conversion

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']
Type:string
Default value:'//TRANSLIT'

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']
Type:array
Default value: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.

Web server settings

$cfg['OBGzip']
Type:string/boolean
Default value:'auto'

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['TrustedProxies']
Type:array
Default value:array()

Lists proxies and HTTP headers which are trusted for $cfg['Servers'][$i]['AllowDeny']['order']. 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']
Type:string
Default value:'auto'

Specifies whether GD >= 2 is available. If yes it can be used for MIME transformations. Possible values are:

  • auto - automatically detect
  • yes - GD 2 functions can be used
  • no - GD 2 function cannot be used
$cfg['CheckConfigurationPermissions']
Type:boolean
Default value:true

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.

$cfg['LinkLengthLimit']
Type:integer
Default value:1000

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 URL .

$cfg['CSPAllow']
Type:string
Default value:''

Additional string to include in allowed script and image sources in Content Security Policy header.

This can be useful when you want to include some external JavaScript files in config.footer.inc.php or config.header.inc.php, which would be normally not allowed by Content Security Policy.

To allow some sites, just list them within the string:

$cfg['CSPAllow'] = 'example.com example.net';

New in version 4.0.4.

$cfg['DisableMultiTableMaintenance']
Type:boolean
Default value:false

In the database Structure page, it’s possible to mark some tables then choose an operation like optimizing for many tables. This can slow down a server; therefore, setting this to true prevents this kind of multiple maintenance operation.

Theme settings

Please directly modify themes/themename/layout.inc.php, although your changes will be overwritten with the next update.

Design customization

Default value:50

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.

Type:string
Default value:'left'

Defines the place where table row links (Edit, Copy, Delete) would be put when tables contents are displayed (you may have them displayed at the left side, right side, both sides or nowhere).

$cfg['RowActionLinksWithoutUnique']
Type:boolean
Default value:false

Defines whether to show row links (Edit, Copy, Delete) and checkboxes for multiple row operations even when the selection does not have a unique key. Using row actions in the absence of a unique key may result in different/more rows being affected since there is no guaranteed way to select the exact row(s).

$cfg['RememberSorting']
Type:boolean
Default value:true

If enabled, remember the sorting of each table when browsing them.

$cfg['TablePrimaryKeyOrder']
Type:string
Default value:'NONE'

Type:boolean
Default value:true

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.

Text fields

$cfg['CharEditing']
Type:string
Default value:'input'

Defines which type of editing controls should be used for CHAR and VARCHAR columns. Applies to data editing and also to the default values in structure editing. 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
$cfg['MinSizeForInputField']
Type:integer
Default value:4

Defines the minimum size for input fields generated for CHAR and VARCHAR columns.

Web server upload/save/import directories

$cfg['UploadDir']
Type:string
Default value:''

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.

Note

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

$cfg['SaveDir']
Type:string
Default value:''

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.

Note

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']
Type:string
Default value:''

The name of the directory where temporary files can be stored.

This is needed for importing ESRI Shapefiles, see 6.30 Import: How can I import ESRI Shapefiles? and to work around limitations of open_basedir for uploaded files, see 1.11 I get an ‘open_basedir restriction’ while uploading a file from the query box..

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.

Various display setting

$cfg['RepeatCells']
Type:integer
Default value:100

Repeat the headers every X cells, or 0 to deactivate.

$cfg['QueryHistoryDB']
Type:boolean
Default value:false
$cfg['QueryHistoryMax']
Type:integer
Default value:25

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'].

$cfg['BrowseMIME']
Type:boolean
Default value:true

Enable Transformations.

$cfg['MaxExactCount']
Type:integer
Default value:500000

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']
Type:integer
Default value:0

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. Setting this to 0 bypasses any row counting.

$cfg['NaturalOrder']
Type:boolean
Default value:true

Sorts database and table names according to natural order (for example, t1, t2, t10). Currently implemented in the navigation panel and in Database view, for the table list.
