Php Include Problem

I have a few php scripts which perform various database queries. Originally
I had them all in the same directory which could be viewed through my apache
web server via http://localhost/admin/. I wanted a couple of the php scripts
to be accessable on their own, so I added another portal to my apache
configuration to allow http://loclahost/test/. I then replicated the entire
/admin/ dir to /test/ with the same permissions and directory structure.
Strangly after doing so, the test setup does not work as wanted. When the
php scripts are run in the test portal, I get include errors. I figured
everything should run smoothly, but obviously not. Please advise if you
have any ideas.
