Help with PHP on Redhat 7.2

Hi,
 I can't seem to get my php to work. When I uncomment the LoadModule lines
and try to start my webserver I get this error:

Invalid command 'LoadModule', perhaps mis-spelled or defined by a module not
included in the server configuration.

I can't remember if I have upgraded the Apache webserver. I understand that
if it is compiled then you must be sure to add the enable-module=so  in your
configure statement.

Can you tell me if the version below is the one that came with Redhat 7.2?

Here is some info.
