1. PHP Application Controller
An application controller in PHP is a term used in web development to describe a component or
group of components in charge of controlling request flow and coordinating the execution of
different operations within a web application.
This is a simple illustration of how an application controller in PHP could be organized:

3. The index.php file serves as the entry point for all requests in this example. It contains all the
necessary files, including the ApplicationController class, functions, and configurations. To handle
the request, it then instantiates the ApplicationController class and invokes its dispatch method.
The ApplicationController class includes methods that map to various actions (like home and
about) that the application can execute. Based on the request parameters (such as $_GET['action']),
the dispatch method chooses which action to take and invokes the relevant method.
