note 9846 modified in array by ronabop

Arrays are never removed from memory, however there is an internal pointer that always points to the "next" array item. After you interate through an array, this will need to be reset back to the first element if you want to access it in a loop again. see the Reset function at http://www.php.net/manual/function.reset.php if you are confused. http://www.php.net/manual/function.array.php
