Apache > PHP configuration

So I have a php script and a new Centos 6.5 server, the centos server has apache and php etc installed, however php scripts are showing as plain text, please see example - [login to view URL] This should be showing a graph from our cacti server. You can see php is installed correctly - [login to view URL] Likely an easy fix for someone, but it has baffled me, please help! We may require additional help to get the script working, but hopefully just a php issue... Looking for someone who can fix this fast, who has skype and potential for future work.
