Apache / PHP / IIS & Win2K Installation problem

Hi, I am a newbie to PHP and have bought some books to help me learn it, unfortunately I cant seem to get any php files to work, I have followed the instructions from these teaching books and from the PHP Manual and still cant get it to work. When I try to do that phpinfo file for example all I see is the code and Windows2000 does not seem to understand the file type and allways asks me what program I would like to install. I have managed to Install Apache on IIS and all seems to be working. I have edited the php.ini file as suggested in the books I bought. I have gone through the instructions on the PHP manual to set up the extension for .php and now I appear to be lost. If you could help I'd be most grateful thanks. Richard.
