LocalHost won't show PHP files

Hi. I've scoured the net, posted tons of forum threads, tried everything. I simply cannot get this to work, yet it should be so simple. I recently had our Admin guy install PHP as a CGI-binary on a Unix system. Apache 1.3.2 is also installed. He didn't install PHP as a Apache module because the server was never configured with axps. Now, I can run PHP scripts at the command line, which is great. However, anytime I visit our server and try to view a *.php page, it just tries to open/save the file, instead of actually displaying HTML. My question is, what do I have to do to enable php to run like this in Apache? Is there something I need to add to httpd.conf to get this to work? I've tried everything and nothing works. Yet in the same folder my *.cgi scripts run flawlessly. Please help. Appreciated. ted
