PHP Extensions

Standard PHP extensions

EasyApache has the ability to install, uninstall, and update several popular PHP extensions as part of the build process. When EasyApache runs, it will automatically determine which extensions are active in the main php.ini file at /usr/local/lib/php.ini. Active extensions will automatically be selected in the EasyApache interface.

Rerunning EasyApache is not required in order to enable or disable the standard PHP extensions. cPanel now provides a tool called /scripts/phpextensionmgr that can also be used for the installation or removal of PHP extensions. For detailed information about this tool, run the following command:

• /scripts/phpextensionmgr --help

Note: The concurrent DSO patch is incompatible with all of the following extensions:

• Suhosin® -- The Suhosin extension for PHP is designed to protect servers and users from flaws in PHP scripts. It is highly configurable and recommended for administrators concerned about the security of their servers. Click here to learn more.
• Zend® Optimizer -- The Zend Optimizer is essential to many hosting providers. In addition to improving the performance of PHP scripts by optimizing PHP bytecode, it allows for the use of Zend Guard encoded scripts. Click here to learn more.
• ionCube® Loader -- While it does not perform any caching or optimizing, this extension allows users to execute ionCube-encoded PHP scripts. Click here to learn more.
• eAccelerator -- This extension is an open-source PHP optimizer and cache. While eAccelerator can be loaded regardless of how PHP is handled, caching only works when PHP is served using DSO or using FCGI. Click here to learn more.
