PHP Options

Last modified: September 26, 2024


Overview

This document lists the PHP options available in EasyApache 4. Select the PHP extensions that you wish to use in WHM’s EasyApache 4 interface (WHM » Home » Software » EasyApache 4) or use your package manager. For more information about how to install a PHP package, read our How to Locate and Install a PHP Version or Extension documentation.

EasyApache 4 adheres to the php.net supported versions timeline. The profiles that we supply in WHM’s EasyApache 4 interface (WHM » Home » Software » EasyApache 4) only provide PHP versions that php.net currently supports.

  • If your server runs AlmaLinux or Rocky Linux™, you cannot use PHP 7.1 or earlier.
  • If your server runs Ubuntu®, you cannot use PHP 7.2 or earlier.
  • Packages for unsupported versions of PHP will remain on the WebPros International, LLC mirrors and servers, but we will not provide any further updates.
Note:

To determine which package installs a specific extension, use the repoquery command. Use the following command to run the query, where ea-php81-php-mysqli represents the extension that you wish to install:

repoquery -q -\-whatprovides 'ea-php81-php-mysqli' | sort -V | tail -1

Current PHP versions

Current versions of PHP include PHP versions 8.1, 8.2, and 8.3. Unless otherwise noted, the following options support all current versions of PHP.

Opcode cachers

An opcode cacher improves the efficiency of your PHP applications but also uses more memory. EasyApache 4 currently only supports the OPCache opcode cacher.

Warning:
  • Opcode caching programs are not compatible with the suPHP or CGI PHP handlers. The caching program either does not function, or functions incorrectly.
  • The system does not automatically configure OPCache. If you do not manually configure OPCache after you install it, it will provide no benefits.

PHP loaders or encoders

A PHP loader allows PHP to execute encoded applications. This ensures that others cannot access your code. You can use one of the following options to install a PHP loader on your web server:

Unless otherwise noted, the following options support all legacy versions of PHP.

Opcode cachers for legacy PHP versions

An opcode cacher improves the efficiency of your PHP applications but also uses more memory.

EasyApache 4 currently only supports the OPCache opcode cacher.

Warning:
  • Opcode caching programs are not compatible with the suPHP or CGI PHP handlers. The caching program either does not function, or functions incorrectly.
  • The system does not automatically configure OPCache. If you do not manually configure OPCache after you install it, it will provide no benefits.

PHP loaders or encoders for legacy PHP versions

A PHP loader allows PHP to execute encoded applications. This ensures that others cannot access your code. You can use one of the following options to install a PHP loader on your web server:

  • SourceGuardian Loader
  • ionCube Loader
    Note:
    • You cannot use ionCube Loader 4 with PHP version 7.0 or later.
    • You cannot use ionCube Loader 5 with PHP version 7.0 or later.
    • You cannot use ionCube Loader 6 with PHP version 7.1 or later.
    • You can only use ionCube 11 with PHP 7.4.
  • Zen Guard Loader — You cannot use Zend Guard Loader with PHP version 7.0 or later.
Note:
  • The Apache information page incorrectly displays Zend Guard Loader as version 3.3. Your version of PHP determines the version of Zend Guard Loader that the system actually uses.
    • If you use PHP versions 5.5 or 5.6, EasyApache uses Zend Guard Loader version 7.0.
    • If you use PHP version 5.4, EasyApache uses Zend Guard Loader version 6.0.
  • The IonCube configuration file name varies based on the version of PHP that you use.
    • If you use PHP versions 5.4 or 5.5, IonCube uses the the ioncube.ini file.
    • If you use PHP version 5.6, IonCube uses the 01-ioncube.ini file.
  • You cannot use multiple versions of ionCube simultaneously.
