Apache - PHP Files Are Returned Black, Not Even HTML in php File Displaying
===

I have Ubuntu 10.04 and my apache2 server has been running for a couple of days now.

I have created a new directory called 'xmlscores' and when I run any PHP file inside of this directory nothing gets returned, not even my HTML that is inside of the page. 

Note: Other File Types open correctly in the browser (I have tried HTML & XML).

This suggests to me that the php code is not even interpreted and thus not even sent to my apache server - my browser, by default, returns blank page (source is blank)

Note: The problem is not with my php code, as I have tried multiple files and none have worked.
