I could have sworn that references and I used to get along... In the menu::hasChild method, I cant seem to reference $this->_data. $this->_data is supposed to be a reference to the original array $array in the local scope. The only way to make this script work is to call on the $GLOBALS array in menu::hasChild. Could anyone explain to me, why I'm unable to use $this->_data in menu::hasChild?

Nevermind. I figured what was causing the problem... New Code: -- Code Snip -- <?php header('content-type: text/plain'); $array = array ( '0000000000000000' => array (
