Upgrading / Installing new versions of PHP via WHM's EasyApache interface.
Upgrading PHP may be done easily from directly within WHM's EasyApache 4 interface. Simply select the Customize option, and navigate to "PHP versions". Here you may select the PHP versions you would like to install. If you select a new version of PHP, the system will detect the PHP extensions that already exist for other installed versions of PHP and include them within the installation.
