Installation problems

I am having problems running php files. I cannot see any of the simple test pages that I have set up in C:\inetpub\wwwroot. I can see the regular html lines but none of the php lines. I have installed the PHP 5 (CGI) with my web server (IIS 5). I have set up the PATH environment variable, my .ini file is in c:\php and I am using PHPRC environment variable to point to it. The rights have been given to the I_User for the folder. Please assist me in getting me up and running with PHP. Thanks
