Can you explain the distribution of responsibilities among components in the MVC architecture?

In MVC (Model-View-Controller) architecture, responsibilities are distributed as follows:

• Model: responsible for data handling and business logic. It interacts with the database, performs calculations, and stores application state.

• View: responsible for displaying data to the user. It receives data from the model and generates the interface (HTML, JSON, etc.).

• Controller: handles user requests, processes them, interacts with the model to get or modify data, and selects the appropriate view for display.

Example in PHP:

class UserController {
    public function show($id) {
        $user = UserModel::find($id); // model
        include 'views/user.php'; // view
    }
}

Thus, MVC separates responsibilities, making maintenance and development easier.
