Here's a tip that may or may not make your life easier. Did you know that you can do both: <input type=whatever name="foo[]" value=whatever> AND <input type=whatever name="foo[$i]" value=whatever> where $i is whatever you want it to be. numbers, strings, etc. the first example auto-assigns the array indices in order starting from 0 (I think) every time you use foo[]. The second example uses your own array indices. And you CAN have non-sequential indices. That way, your script can deal exclusively with the foo array and never have to go back and forth between foo[x] and foox. That little feature has made my life much easier on several occasions.
