How to Limit Available PHP Versions in MultiPHP Manager and Manage php.ini Directives with

1. Limit Available PHP Versions in MultiPHP Manager

cPanel & WHM allows administrators to restrict which PHP versions appear to users in the MultiPHP Manager interface. This is useful for preventing access to legacy PHP versions or avoiding early upgrades to newer versions.

Important: Users can bypass restrictions by manually setting a PHP version in an .htaccess file. This feature only limits the versions displayed in MultiPHP Manager.

1.1 Requirements

PHP version restrictions require:

• A Feature List
• An Account Package
• Installed PHP versions

By default, all installed PHP versions are visible to all accounts unless restricted.

1.2 How to Set PHP Version Restrictions

1. Create or edit a Feature List in WHM’s Feature Manager:
   WHM » Home » Packages » Feature Manager


2. Deselect any PHP versions you want to hide from users.
   Notes:
   • Newly installed PHP versions are visible to all users by default.
   • Restrictions apply to all EasyApache 4 PHP versions, including custom packages.


3. Create or edit a Package in WHM:
   WHM » Home » Packages » Add a Package
   or
   WHM » Home » Packages » Edit a Package


4. Assign the Feature List to the Package.


5. Assign the Package to user accounts in WHM’s Modify an Account interface:
   WHM » Home » Account Functions » Modify an Account

1.3 Limitations

If PHP restrictions are applied, users cannot select restricted versions in MultiPHP Manager. However, administrators can still assign restricted versions manually, allowing users to remain on legacy versions without being able to switch back to them later.

2. Manage php.ini Directives with PHP‑FPM

This section explains how to manage php.ini directives when PHP‑FPM is enabled.

Note: You can edit php.ini directives at both the domain and system level using WHM’s MultiPHP Manager.

2.1 Confirm PHP‑FPM Is Enabled

1. Log in to WHM as root.
2. Navigate to:
   WHM » Home » Software » MultiPHP Manager
3. Locate the domain and ensure the PHP‑FPM toggle is set to On.

PHP‑FPM is enabled by default.

2.2 Create a phpinfo File

Use a phpinfo file to view the domain’s PHP configuration.

1. SSH into the server as root.
2. Navigate to the domain’s document root.
3. Create a file named phpinfo.php with the following content:

Set ownership and permissions:

chmod 0644 /home/username/public_html/phpinfo.php
chown username.username /home/username/public_html/phpinfo.php

Visit:
https://example.com/phpinfo.php
If PHP‑FPM is active, the ServerAPI value will show FPM/FastCGI.

2.3 Review php.ini Directives

You can review directives in:

• cPanel’s MultiPHP INI Editor (per‑domain)
• WHM’s MultiPHP INI Editor (global)

Default PHP‑FPM directives include:

php_admin_flag[allow_url_fopen] = on
php_admin_flag[log_errors] = on
php_admin_value[disable_functions] = exec,passthru,shell_exec,system
php_admin_value[doc_root] = "/home/username/public_html"
php_admin_value[error_log] = /home/username/logs/domain_com.php.error.log
php_admin_value[short_open_tag] = on
php_value[error_reporting] = E_ALL & ~E_NOTICE

3. Modify php.ini Directives

3.1 Modify Directives Globally

Use WHM’s MultiPHP INI Editor to modify global php.ini settings.

To modify PHP‑FPM pool settings:

1. SSH into the server.
2. Create the directory:
   /var/cpanel/ApachePHPFPM
3. Create the file:
   /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml
4. Add directives, for example:

---
php_admin_value_memory_limit: { name: 'php_admin_value[memory_limit]', value: 120M }

Rebuild PHP‑FPM configuration:

/usr/local/cpanel/scripts/php_fpm_config --rebuild

Restart services:

/usr/local/cpanel/scripts/restartsrv_apache_php_fpm
/usr/local/cpanel/scripts/restartsrv_httpd

3.2 Modify Directives for a Single Domain

1. SSH into the server.
2. Create the file:
   /var/cpanel/userdata/username/domain.com.php-fpm.yaml
3. Add directives, for example:

Disable passthru and system:

---
_is_present: 1
php_admin_value_disable_functions: { name: 'php_admin_value[disable_functions]', value: passthru,system }

Enable all functions:

---
_is_present: 1
php_admin_value_disable_functions: { name: 'php_admin_value[disable_functions]', value: none }

Rebuild PHP‑FPM configuration:

/usr/local/cpanel/scripts/php_fpm_config --rebuild

Restart services:

/usr/local/cpanel/scripts/restartsrv_apache_php_fpm
/usr/local/cpanel/scripts/restartsrv_httpd
