How can the concept of design patterns be applied to improve the structure of PHP scripts that generate HTML content on a WordPress site?

When generating HTML content on a WordPress site using PHP scripts, it's important to follow design patterns to improve the structure and maintainability of the code. One way to achieve this is by using the Model-View-Controller (MVC) design pattern. By separating the business logic (Model), presentation logic (View), and user input handling (Controller), the code becomes more organized and easier to maintain.

// Controller (index.php)
class Controller {
    public function displayPage() {
        $model = new Model();
        $data = $model->getData();
        
        $view = new View();
        $view->renderPage($data);
    }
}

// Model (model.php)
class Model {
    public function getData() {
        // Database queries or other data retrieval logic
        return $data;
    }
}

// View (view.php)
class View {
    public function renderPage($data) {
        // HTML content generation using $data
    }
}

$controller = new Controller();
$controller->displayPage();
