That was how I was going to do it when I was going to capture the entire record for each item, so I'd end up with a set of data for each item:

description0 = My item
type0 = treadmill
serial0 = 12345
recid0 = 5001

and so on...

But i could potentially end up with a HUGE bunch of data. I like your method much better.

I'm going to use RECID, which is always unique.

Thanks for your help!

Now that I'm looking at your code, I'm getting it... scratch my stupid array question.

Here's another one for you though, pertaining to PHP:

Is it better, in a multi-predicate IF statement, to use && instead of "and"?

I've always written

if (($x = 1) and ($y=3)){

Is && a better way?
