Apache missing php module

I installed httpd v2.2.15 and php v5.5.13 via yum. I first noticed the problem when I tried to access my site and it displayed the PHP code. Then I discovered that there is no php module in /etc/httpd/modules so the LoadModule fails.

How can I add the php module to apache? the php website refers to building it from source. However I need to manage this via RPMs. Are there any alternative ways of doing this?

Here are the httpd RPMs I've installed:

httpd-tools-2.2.15-30.el6.centos.x86_64
httpd-2.2.15-30.el6.centos.x86_64
httpd-devel-2.2.15-30.el6.centos.x86_64
