PHP Probs

Hi, I've just installed PHP only to find that it isnt working properly.. I followed all instructions on online documentation and files that came with the program. I'm running Apache1.3.12 and have PHP4.0.0 and my operating system is Linux Redhat 6.0 When opening a php file it shows the actual code instead of the page that it should.. I've been installing/reinstalling for paste few days trying to get it to work without any luck :( A sample of a page on my server can be found here http://lanithium.staticky.com/w-agora/admin.php3 This is a php package that i found on a site.... If anyone can help please do so as i really want to broaden my coding skills into php.. and its bloody frustrating not being able to get it to work :( Thanks in advance, Matt lanithium@dingoblue.net.au
