How can the EVA pattern be applied in PHP development to improve code maintainability and readability?

Issue: The EVA pattern (Entity-View-Action) can be applied in PHP development to improve code maintainability and readability by separating the concerns of data manipulation (Entity), presentation (View), and business logic (Action). This separation of concerns makes the code easier to understand, test, and maintain. PHP Code Snippet: 

// Entity class
class User {
    private $id;
    private $name;
    
    public function __construct($id, $name) {
        $this->id = $id;
        $this->name = $name;
    }
    
    // Getters and setters
}

// View class
class UserView {
    public function render(User $user) {
        return "<p>User ID: {$user->getId()}, Name: {$user->getName()}</p>";
    }
}

// Action class
class UserController {
    public function getUserById($userId) {
        // Database query to fetch user data
        $userData = // fetch user data by $userId
        
        $user = new User($userData['id'], $userData['name']);
        
        return $user;
    }
}

// Implementation
$userController = new UserController();
$user = $userController->getUserById(1);

$userView = new UserView();
echo $userView->render($user);
