Processing incrementing variable names?

[Anon]

I have a form and it passes over form field names that increment ex: ProductIDx where x goes from 0 to 300. I want to know how to process ProductIDx when the form is submitted.

ex: print "$ProductID".x

or something like that, but that doesn't work. I'm looking for something that does. Thank you.

You need variable variables:

$variable_variable = "ProductID$x"; //where $x is your incrementing number
print $$variable_variable;

Is there documentation on this type of thing?

Yes there is documentation on this:
http://www.php.net/manual/en/language.variables.variable.php

Plus if you search though these message boards you'll find your question gets asked about 1 a week or so.
