Apache2 & php5 Problem

[Randy Patterson <tech@patterson-pcc.com>]

I am trying to setup a local web server on my machine to test php projects 
before going live. I have installed apache2, php5 and mysql using aptitude 
and apache and mysql seem to be working fine. I try to load a test page in a 
browser;

http://localhost/apache2-default/test.php

The file contains a test message between header tags <h1></h1> and below that 
a php script line that just prints another test message with the 'print' 
command. The browser displays the first HTML message but not the message from 
the php script line. There are no errors messages. Is there some 
configuration that needs to take place after installing php5 with aptitude?

Thanks,
Randy
