    public function __construct() { }
    public function key() { }
    public function current() { }
    function next() { }
    function valid() { }
    function rewind() { }
}
class DerivedClass extends IteratorClass { }
class NonIterator { }

function dump_iterateable($class) {
    $reflection = new ReflectionClass($class);
    var_dump($reflection->isIterateable());
}

$classes = array("ArrayObject", "IteratorClass", "DerivedClass", "NonIterator");

foreach ($classes as $class) {
    echo "Is $class iterateable? ";
    dump_iterateable($class);
}
?>
