Well, I was trying to use Apache 1.3 and php 4, but I said screw it and got someone to download a copy of Apache 2.2.6 and PHP 5.2.5. I installed everything newly and it all works now.
Except that Apache is not reading out of the DocumentRoot directory as it should. I changed the httpd.conf file to point to the directory "/Library/WebServer/Documents/" which is where all my pages where set up on the last Apache. But for some reason, it's not reading from that dir. It still seems to be reading from the default "/usr/htdocs/". But the problem is that I replaced the index page in that directory, and it still shows it. Everytime I go to localhost in my browser, it just says "IT WORKS!" and doesn't show my index page.
I don't understand.

I've learned more Unix in the past 2 weeks than I have in 20 years.
