How important is it to follow the EVA principle in PHP programming, and how does it impact code readability and maintenance?

It is crucial to follow the EVA principle in PHP programming as it promotes code readability, maintainability, and scalability. By separating concerns into entities, views, and actions, it makes the codebase more organized and easier to understand for developers. 

// Example of implementing the EVA principle in PHP

// Entity class
class User {
    private $name;
    
    public function getName() {
        return $this->name;
    }
    
    public function setName($name) {
        $this->name = $name;
    }
}

// View class
class UserView {
    public function displayUserInfo(User $user) {
        echo "User Name: " . $user->getName();
    }
}

// Action class
class UserController {
    public function showUserInfo(User $user) {
        $view = new UserView();
        $view->displayUserInfo($user);
    }
}

// Implementation
$user = new User();
$user->setName("John Doe");

$controller = new UserController();
$controller->showUserInfo($user);
