Recursive Array Iterator

Im trying to figure out how to create this. But Im stuck in the foreach loop. For some reason, $value in the foreach loop is not an object (Isn't is supposed to be?) Any hints to get me in the right direction. Thanks $array = array(1 => array(2 => array(3 => array(4)))); class recursiveArrayIterator extends ArrayIterator implements RecursiveIterator { function __construct($array) {

       parent::__construct( $array );

} function hasChildren() { } function getChildren() { } } $obj = new recursiveArrayIterator( $array ); //reflectionObject::export($obj); foreach($obj as $value) { var_dump($value); }
