Centos 6.7 (Final) comes with PHP 5.3.3, but the site running on the server needed PHP 5.2.17. Because it is not supported much anymore I manually configured PHP 5.2.17 using this guide: PHP Configuration Guide
I got PHP 5.2.17 configured on the server, yet that didn't fix the errors I was having, so I am trying to revert back to 5.3.3.
php -v returns:
