I'm going to tentatively move this to Linux - Software as this question does not appear to be Arch related/specific.
Please correct me if I'm wrong, otherwise it will be moved shortly.
As for an answer to your question:
How did you install the files listed above? You need to setup Apache to work with PHP as defined:
http://www.php.net/manual/en/install.apache.php
But this would also depend on which versions of the above applications you have installed. Please provide us with some information
Which distro?
Which versions of apps?
How did you install them?
Cool
