undefined index ??

Hi,

What's an undefined index ??? I'm going through my error_log for apache and there are tons on them, are they important or is my error reporting set to high (it's set at e_all at the moment) ??

Thanks,

Jon

oops, sorry, forgot to mention language! php 4.3.4 Mac OS X 10.3

Thanks,

This typically means you're trying to access the nth (or higher) element of an array of size n, whose highest element should be indexed n-1. Check any for loops iterating against an array, and check all references to elements within arrays to make sure you're not trying to access an index that's not there.
