Question

CodeIgniter

protected function tryRunMethod($controller, $method)
    {
        try {
            $controller->$method();
        } catch (\Exception $e) {
            $this->sandResponseCode(Response::HTTP_METHOD_NOT_ALLOWED);
            throw new \Exception($e);
        }
    }

How to make this piece better and get rid of this recommendatory inscription?

Answer 1

i would try that

protected function tryRunMethod(Object $controller, $method)
    {
        try {
            $controller->$method();
        } catch (\Exception $e) {
            $this->sandResponseCode(Response::HTTP_METHOD_NOT_ALLOWED);
            throw new \Exception($e);
        }
    }

or better yet, specify which class $controller is an instance of

protected function tryRunMethod(ControllerClass $controller, $method)
    {
     ...
    }
