How does the MVC pattern help in organizing PHP projects and improving code maintainability?

The MVC pattern helps in organizing PHP projects by separating the application into three main components: Model, View, and Controller. This separation allows for better code organization, easier maintenance, and improved scalability. By separating concerns, developers can work on different parts of the application independently, making it easier to understand, modify, and extend the codebase. 

// Example of implementing the MVC pattern in a PHP project

// Model (data layer)
class User {
    public function getUserById($id) {
        // fetch user data from database
    }
}

// View (presentation layer)
class UserView {
    public function displayUser($userData) {
        // display user data in HTML format
    }
}

// Controller (business logic layer)
class UserController {
    public function showUser($userId) {
        $userModel = new User();
        $userData = $userModel->getUserById($userId);
        
        $userView = new UserView();
        $userView->displayUser($userData);
    }
}

// Usage
$userController = new UserController();
$userController->showUser(1);
