Re: Foreach Array Help

First of all, thanks for the response. Here is where I am getting lost: In $code['assign'][1] - "1" is the assignment ID, and I would like the array to be able to hold a billion of these different assignments all with conceivably a billion codeapply ID as in $code['assign'][1]['codeapply'][3], where "3" is the codeapply value. In other words, because each of these items directly under assign and codeapply are arrays because they hold sub-info, I have made the keys of these items the values. So - am I approaching this whole array thing wrong? Thanks. "Rob Adams" <rob_adams@hotmail.com> wrote in message news:20031014134556.6177.qmail@pb1.pair.com... > > "Jed R.
