Question

I have followed this nice video tutorial to create a mini MVC PHP framework.

As you can see, the guy creates an action called home() inside the Controller class to show the main page.

Now, I need to create another action called foobar() that shows another page, but how can i associated it to an url in a simple way?

Answer 1

This is usually done by routing. If the first part of the URL identifies the controller and the second the action, you extract those variables and route accordingly.

A very basic example:

$action = 'foobar';
$controllerName = 'whatever';

if(class_exists($controllerName)){

    $controller = new $controllerName;

    if(method_exists($controller, $action)){

        $controller->$action();

    }
}

Obviously, $action and $controllerName are obtained from the URL.

This code snippet tries to call the method ‘foobar’ inside a class named ‘whatever’.
