The default PHP version on our Enterprise Hosting plans is v5.2.17. You can change to PHP 5.3 or PHP 5.4 by following the instructions below:
1. Login to cPanel
2. Search for the 'Apache Handlers' option and click it.
3. Once at the Apache Handlers page, type in the following:
Handler: application/x-httpd-php53 Exention(s): php
Now all .php files will be executed using PHP 5.3.
