'.php';    $class = new ReflectionClass($class_name);    if (class_exists($class_name)) {      if ($class->hasMethod($method_name)) {        $func = $class->getmethod($method_name);        $instance = $class->newInstance();        $func->invokeArgs($instance, array($_REQUEST));        $result = $instance->getResult();        echo $result;      }    }  } catch (Exception $exc) {    echo $exc->getTraceAsString();  }}?>
