Title: Update ArrayStack.php

Array object cannot be defined twice, this is a minor typo because it is not the php ArrayObject that is needed in this, but the Stdlib\ArrayObject.

stack call:
Fatal error: Cannot use ArrayObject as ArrayObject because the name is already in use

error is found with the
skeleton application
doctrine module
doctrine orm module
doctrine dbal
