PHP Versions

The PHP Versions page lets you install, manage, and configure the supported PHP versions on the server, across every available engine on a single page.

Overview

URL: /admin/settings/php-manager-versions

Navigate to Settings > PHP > PHP Versions.

The PHP area has two tabs across the top of the content, and each one is a page in its own right:

Tab	Address	Documented in
Versions	/admin/settings/php-manager-versions	This page.
Domain Assignment	/admin/settings/php-manager-domains	Multi PHP Domains Manager

The counter next to Versions shows how many versions are installed out of the total, and the one next to Domain Assignment counts the domains on the server.

The page shows summary counters (Total, Installed, Available, Repositories) and a card for every supported PHP version. Each card shows the version, its repository (engine), whether it is Installed or Not Installed, and an Install, Configure, or Uninstall action. A search box above the cards filters by version, name, or repository.

PHP versions come from up to three repositories, selected with the filter chips above the card list:

• REMI - standard PHP for Apache (mod_php / PHP-FPM).
• LiteSpeed - LSPHP builds served through LSAPI, used when LiteSpeed is the active web server.
• CloudLinux - Alt-PHP, available after a CloudLinux conversion, including legacy versions down to PHP 5.2.

The REMI repository is always present; LiteSpeed appears once the LiteSpeed module is installed, and CloudLinux (Alt-PHP) appears after conversion, each as an extra chip alongside All. Assign domains and plans to the matching engine on the Domain Assignment tab and, for LiteSpeed, the PHP Migration page.

Configuring a PHP Version

Configure on an installed version opens the configuration page for that version, at /admin/php-versions/<id>/configure. That page sits outside the Settings area, so the Settings groups are replaced by a PHP Versions breadcrumb that takes you back.

PHP Profile

At the top, a PHP Profile dropdown allows selecting which configuration profile to edit (e.g., "PHP 8.4 - Default (default, php)"). An options menu (three dots) is available next to the profile selector.

Service Status

A status banner shows whether the PHP-FPM service is running, with a Check Service Status button.
