What is the difference between using a pre-existing MVC pattern and creating a custom one for PHP development?

Using a pre-existing MVC pattern like Laravel or Symfony can save time and provide a standardized structure for your PHP development. However, creating a custom MVC pattern allows for more flexibility and customization to fit the specific needs of your project.

// Custom MVC pattern implementation in PHP

// Model
class User {
    public function getAllUsers() {
        // Database query to get all users
    }
}

// View
class UserView {
    public function showAllUsers($users) {
        // Display all users in a formatted way
    }
}

// Controller
class UserController {
    private $model;
    private $view;

    public function __construct(User $model, UserView $view) {
        $this->model = $model;
        $this->view = $view;
    }

    public function showAllUsers() {
        $users = $this->model->getAllUsers();
        $this->view->showAllUsers($users);
    }
}

// Implementation
$model = new User();
$view = new UserView();
$controller = new UserController($model, $view);

$controller->showAllUsers();
