What are the common misconceptions or pitfalls developers may encounter when trying to implement the MVC pattern in PHP, and how can they be avoided?

One common misconception when implementing the MVC pattern in PHP is not properly separating the concerns of the model, view, and controller. To avoid this, make sure to clearly define the responsibilities of each component and avoid mixing logic between them. 

// Incorrect implementation
class UserController {
    public function getUserData() {
        $user = new User();
        $userData = $user->getData();
        require_once('user_view.php');
    }
}

// Correct implementation
class UserController {
    public function getUserData() {
        $userModel = new UserModel();
        $userData = $userModel->getData();
        $userView = new UserView();
        $userView->render($userData);
    }
}
