array_key_exists is not working for large multidimensional array. For ex

$arr=array( '1'=>10,
       '2'=>array('21'=>21,
                  '22'=>22,
                  '23'=>array('test'=>100,
                              '231'=>231),
                 ),
       '3'=>30,
       '4'=>40 
      );

array_key_exists('test',$arr) returns 'false' but it works with some simple arrays.
