I require some assistance in a confusing matter. I have for months been running my PHP codes thru a free web hoster and things worked great. Recently I decided to run the site from my own drive. So I set up Apache and PHP4 and the tests worked great. But once I tried to run my own PHP codes, a few of the pages that always worked before started coming up with errors like "undefined variable" and "undefined offset". These errors never appeared when i ran them online and I have made no changes to to code to cause them. Help!!!
