Lesson 4 - E-shop in PHP - Controller action design

In the previous lesson, E-shop in PHP - App folder and making the project runnable, we added the last couple of changes needed to our project directory structure and made the project functional again. Although the new architecture makes the project much clearer, the framework still lacks a lot a functionality needed to build a large application. Mainly, our framework suffers from these 2 issues:

Each controller can only perform a single action (the index() method), which leads to either long methods or the exponential growth of the number of controllers alongside the application's complexity. Also, there's no way for a controller to work with an API, e.g. for AJAX.
Real commercial applications are based on forms. Up until now, we've written all of our forms manually, where the templates weren't very pretty (they were large and had us fill the data in manually). We had to manually write in a validation for every single form and implement code that retrieved $_POST data over and over again. This way, if we gave it enough time, we'd type ourselves to death.

Today's tutorial is about modifying the controller's design.
