What are some best practices for structuring PHP code to achieve specific functionalities on a website?

When structuring PHP code to achieve specific functionalities on a website, it is essential to follow best practices such as using object-oriented programming principles, separating concerns by dividing code into logical components, and implementing design patterns like MVC (Model-View-Controller). This helps in improving code readability, maintainability, and scalability. 

// Example of implementing MVC structure in PHP

// Model - Represents the data and business logic
class UserModel {
    public function getUser($id) {
        // Code to fetch user data from database
    }
}

// View - Represents the presentation layer
class UserView {
    public function displayUser($userData) {
        // Code to display user data in HTML
    }
}

// Controller - Acts as an intermediary between Model and View
class UserController {
    private $model;
    private $view;

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

    public function showUser($id) {
        $userData = $this->model->getUser($id);
        $this->view->displayUser($userData);
    }
}

// Implementation
$model = new UserModel();
$view = new UserView();
$controller = new UserController($model, $view);
$controller->showUser(1);
