Do you use the MVC architectural pattern when developing REST API?

Yes, the architectural pattern MVC (Model-View-Controller) is often used in developing REST APIs in PHP, although in the context of APIs, the concept of "View" may be less pronounced.

• Model is responsible for data handling and business logic.
• Controller processes incoming HTTP requests, calls model methods, and forms the response.
• View in REST API is usually represented by forming a JSON or XML response.

Example of a simple controller in PHP:

class UserController {
    public function getUser($id) {
        $user = UserModel::find($id);
        header('Content-Type: application/json');
        echo json_encode($user);
    }
}

Thus, MVC helps structure the code by dividing responsibilities and facilitating maintenance.
