As someone else said before, I feel you may be thinking in the wrong direction. If you could give us a couple of examples of data you might expect to see in your $_POST aray, and what you wish to produce from it -- e.g. a sample of the final results from the provided data -- we might be able to provide the *real* solution to your problem, not try to shoehorn it into what might be an inappropriate one. In short, give us (a) sample input and (b) desired output, and see what suggestions come up for getting from (a) to (b) -- you might be surprised at how different they are from what you expect! ;) Cheers!
