In what ways can the MVC (Model-View-Controller) pattern be implemented in PHP to enhance modularity and abstraction in web development projects?

To enhance modularity and abstraction in web development projects, the MVC pattern can be implemented in PHP by separating the application logic into three components - the Model (for data manipulation), the View (for user interface), and the Controller (for handling user inputs and interactions). 

// Model - responsible for data manipulation
class UserModel {
    public function getUserData($userId) {
        // logic to fetch user data from database
    }
}

// View - responsible for user interface
class UserView {
    public function displayUserInfo($userData) {
        // display user information on the webpage
    }
}

// Controller - responsible for handling user inputs and interactions
class UserController {
    private $model;
    private $view;

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

    public function showUser($userId) {
        $userData = $this->model->getUserData($userId);
        $this->view->displayUserInfo($userData);
    }
}

// Implementation
$controller = new UserController();
$controller->showUser(1);
