<?phpinterface foo { }class bar implements foo {}print_r(class_implements(new bar));// since PHP 5.1.0 you may also specify the parameter as a stringprint_r(class_implements('bar'));function __autoload($class_name) { require_once $class_name . '.php';}// use __autoload to load the 'not_loaded' classprint_r(class_implements('not_loaded', true));?>
