Per-User php.ini

To enable a per-user php.ini, you can use either PHPRC or PHP_INI_SCAN_DIR. If using CloudLinux and CL PHP Selector, please refer to CloudLinux documentation.

To apply per-user php.ini to all cPanel virtual hosts globally, you can use PHPRC or PHP_INI_SCAN_DIR in LiteSpeed PHP Environment configuration. To apply per-user php.ini to any particular apache virtual host, you can use PHPRC or PHP_INI_SCAN_DIR in that cPanel apache virtual host include file.

To apply per-user php.ini to all virtual hosts globally

To apply per-user php.ini to all virtual hosts globally, you can use either PHPRC or PHP_INI_SCAN_DIR at LSWS Web Admin Console > PHP > Environment as well as LSWS Web Admin Console > External App > lsphpxx -> Environment(need to apply to all lsphpxx). PHPRC will replace your ea-phpxx php.ini with a new php.ini at specified user's location, while PHP_INI_SCAN_DIR will load default ea-phpxx php.ini as well as aditional *.ini.

PHPRC in the WebAdmin Console

Defining the PHPRC environment variable in the WebAdmin console allows you to use a variable that can set a standard location for the php.ini file in each virtual host. This method is also applicable to a control panel environment such as cPanel, but it will modify the behavior of any virtual hosts using this external application. Therefore, adding an individual include file for that host Apache configuration is normally recommended as described as above.

In your external application Environment setting (WebAdmin console > Server > External App > lsphp), enter: PHPRC=variable/php.ini/directory

Example:

PHPRC=$VH_ROOT/public_html

The variables available for use are:

  1. $VH_ROOT: the virtual host's home directory
  2. $VH_NAME: the virtual host's domain
  3. $VH_USER: the virtual host's user

Note

Using this method will cause LSWS to ignore any global php.ini files and only use the user-defined php.ini. However, if no user-defined php.ini is found, LSWS will still use the global php.ini.

Starting from LSWS v5.3.x, LSWS may automatically configure external applications and script handlers for control panels, hence it may not have external applications or script handlers anymore. If you want to define the PHPRC environment variable for all external applications, you can use the PHP tab:

!PHP Tab

PHP_INI_SCAN_DIR in the WebAdmin Console

Using the PHP_INI_SCAN_DIR environment variable allows you to set a standard location for the php.ini file for each virtual host. Unlike the PHPRC environment variable, though, PHP_INI_SCAN_DIR allows the use of the global php.ini file with the addition of a per-user php.ini.

On cPanel, ea-phpxx will normally load the main php.ini, then scan additional .ini files, like in this example with ea-php73:

!Per User PHP

To avoid missing any additional folders when scanning from /opt/cpanel/ea-php73/root/etc/php.d, you should specify multiple additional scanning folders in PHP_INI_SCAN_DIR, separating them with :.

In your external application Environment setting (WebAdmin Console > Server > External App > lsphp73), enter:

PHP_INI_SCAN_DIR=/opt/cpanel/ea-php73/root/etc/php.d:$VH_ROOT/public_html

or simply:

PHP_INI_SCAN_DIR=:$VH_ROOT/public_html

!Per User PHP

After you save the change and restart LSWS, the phpinfo page of the accounts using lsphp73 should change to something similar to the following by scanning additional .ini for additional folders from $VH_ROOT/public_html:

!Per User PHP

The variables available for use are:

  1. $VH_ROOT: the virtual host's home directory
  2. $VH_NAME: the virtual host's domain
  3. $VH_USER: the virtual host's user

Note

  • This method is not recommended if you replace Apache with suPHP. When replacing Apache with suPHP, the PHPRC environment variable is recommended.
  • The PHP_INI_SCAN_DIR environment variable is available for PHP 5.2.7 and up.

Starting from LSWS v5.3.x, LSWS may automatically configure external applications and script handlers for control panels, hence it may not have external applications or script handlers anymore. If you want to define the PHPRC environment variable for all external applications, you can use the PHP tab.

To apply per-user php.ini to a particular virtaul hosts

To define PHPRC or PHP_INI_SCAN_DIR for a particular domain/virtual host on cPanel, you will need to create an include file and define PHPRC or PHP_INI_SCAN_DIR in it.

Most likely you will need to install an extra Apache module first:

$ sudo yum install ea-apache24-mod_env

or something similar, otherwise Apache may return an error like the following:

Apr 05 16:21:46 cptest.com restartsrv_httpd[21931]: AH00526: Syntax error on line 1 of /etc/apache2/conf.d/userdata/std/2_4/wpuser99/wpuser99.com/ini.conf:
Apr 05 16:21:46 cptest.com restartsrv_httpd[21931]: Invalid command 'SetEnv', perhaps misspelled or defined by a module not included in the server configuration

For example, on an EA4 CentOS 7 server, to enable custom php.ini for yourdomain.com, create the file

/etc/apache2/conf.d/userdata/std/2_4/$USER/yourdomain.com/customphpini.conf

add:

PHP_INI_SCAN_DIR=/home/$USER/public_html/
or

SetEnv PHPRC /home/$USER/public_html/

Then make it virtual host include file enabled:

$ sudo vi /etc/apache2/conf/httpd.conf

Include "/etc/apache2/conf.d/userdata/std/2_4/$USER/yourdomain.com/*.conf"
Please be aware that you need to be very careful before you set the above up. cPanel EA4 only reads this specified php.ini when the PHPRC is set. It won't read EA4 original php.ini and modules in the scan folder. If the user-specified php.ini doesn't include a complete set of modules, it may lead to errors, for example, MySQL missing.

Please refer to The cPanel PHPRC PHP Patch for EasyApache 4.

Can I use .user.ini with LiteSpeed Web Server?

It is not recommended to use .user.ini with LSWS, since it is part of cPanel's MultiPHP manager function, and is intended for Apache PHP-FPM. It is not intended for use with LiteSpeed Web Server.

When a user logs into cPanel and edits PHP settings through cPanel's cPanelMultiPHP INI Editor ( cPanel > Home > Software > MultiPHP INI Editor), the editor will save changes to three files in /home/$USER/public_html/: the php.ini file, the .user.ini file, and the .htaccess file.

For example:

  [/home/user1/public_html]# ll
  -rw-r--r--  1 user1 user1 4484 Aug 29 12:25 .htaccess
  -rw-r--r--  1 user1 user1  576 Aug 29 12:25 php.ini
  -rw-r--r--  1 user1 user1  582 Aug 29 12:25 .user.ini

You have probably noticed that the same changes are being saved to three different files at the same time. This is because different PHP handlers will use different files to apply the settings. A user may change the handler at some point, and the three files will be updated accordingly to ensure the cPanel MultiPHP INI Editor settings will continue to apply.

Apache SuPHP uses php.ini.

Apache PHP CGI and PHP-FPM use .user.ini.

CloudLinux mod_lsapi for Apache uses .htaccess.

LiteSpeed uses .htaccess.

LiteSpeed is compatible with cPanel MultiPHP INI Editor out of the box with no extra configuration required. Please also keep in mind that you cannot manually change settings in any of the files through SSH. You must use cPanel MultiPhP INI Editor GUI to make any changes for your test.

If at any time you explicitly want to apply /home/$USER/public_html/.user.ini, regardless of the cPanel default multi-file implementation, you will need to use PHP_INI_SCAN_DIR to manually set it up as instructed earlier in this documentation. However, this is not recommended, and you are encouraged to just use cPanel MultiPHP INI Editor.
