		$data = array();
		array_walk_recursive($arr, array(self, 'appendToArray'), &$data);
		return $data;
	}

	protected static function appendToArray($val, $key, array &$arr) {
		$arr[] = $val;
	}
}

$arr = array(
	'a',
	array(
		'b',
		array(
			'c',
			'd',
		),
	),
);

print_r(TestArray::flatten($arr));
?>

    [1] => b
    [2] => c
    [3] => d
)
