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);
}
?>
