I am trying to learn PHP and gave up onIIS after continually running into PHP limitations. I installed Apache 2.0.55 on my XP Pro system. Apache seems to be working properly, html is OK. But it does not recognize PHP. When I attempt to access a .php page, I get a message box "Do you want to open or save this file". I re-checked the install instructions and don't see what I missed. Can anyone tell me what I did wrong? Thanks.
