HMVC Routes: Protected methods result in warning instead of 404

I've been using HMVC modular extensions. I have a base class in which I've defined some protected methods available to all inheriting controller, however I don't want them to be accessible using URL. When trying to access with URL, I get a warning instead of 404 error. It would be great if these could return 404 as I believe only public methods are intended to be available as routes.

Code:

Severity: Warning

Message: call_user_func_array() expects parameter 1 to be a valid callback, cannot access protected method Controller::method()

Filename: core/CodeIgniter.php

Line Number: 532

Maybe you could use the _remap method in your controllers. Have a check in that method that checks if the called method is public.

remapping-method-calls

You could then use something like this

PHP Code:

public function _remap($method, $params = array())
{
    if( method_exists($this, $method) )
    {
        $reflection = new ReflectionMethod(get_class($this), $method);
        if( $reflection->isPublic() )
        {
            return call_user_func_array(array($this, $method), $params);
        }
        else
        {
            show_404();
        }
    }

    show_404();
}
