Second, to manually loop through an array, use: http://nl.php.net/manual/en/function.prev.php http://nl.php.net/manual/en/function.next.php http://nl.php.net/manual/en/function.current.php http://nl.php.net/manual/en/function.reset.php http://nl.php.net/manual/en/function.end.php Third, don't rely on the order your array elements are given to you by post data. Rather just use foreach() and (ignore|do something else with) the key-value pairs you don't want for this thing. Fourth, I hope I'm not spoiling Jay Blanchard statement on how uncredibly great this online PHP Manual is since you could probably find all the answers to array related questions right here: http://nl.php.net/manual/en/ref.array.php And all you other answers around here: http://nl.php.net/docs.php and here http://www.google.com
