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