I got mine to work. I've been out of town so sorry for the late reply. Basically, what was causing my trouble was that I was creating the .php file in Notepad which made it a text file. This kept the browser from interpreting the file and just displayed it, no matter what was in it. Even changing the name to test.php didn't fix the problem. I had to create the file in Netscape Composer and save it as test.php. Once I did this, everything worked as expected. I can now create the files in Notepad and it works also. I'm not sure why this would be the case. One other main thing I changed was the file association with an application in XP such that all .php files are associated with php.exe instead of what XP had created as a default which was Notepad. As stated earlier, I did not have this problem in Win9x or Win2000. Anyone else having problems of this nature may want to try this to see if it helps.
Also, to answer the questions posed earlier:
Apache is running as a service, version 1.3.20
PHP is running as a module, version 4.1.0
Thanks for the replies! Christmas holidays had me out of town for a while.
