What are some best practices for organizing PHP code to improve readability and maintainability, especially when dealing with database operations?

When dealing with database operations in PHP, it is essential to organize your code in a clear and structured manner to improve readability and maintainability. One best practice is to separate your database logic from your presentation logic by using a design pattern like MVC (Model-View-Controller). This separation allows for easier debugging, testing, and future modifications. 

// Example of organizing PHP code using MVC pattern for database operations

// Model (database logic)
class User {
    public function getAllUsers() {
        // Database query to retrieve all users
    }

    public function getUserById($id) {
        // Database query to retrieve user by ID
    }

    public function updateUser($id, $data) {
        // Database query to update user information
    }
}

// Controller (presentation logic)
class UserController {
    public function showAllUsers() {
        $userModel = new User();
        $users = $userModel->getAllUsers();
        
        // Display users in the view
    }

    public function showUser($id) {
        $userModel = new User();
        $user = $userModel->getUserById($id);
        
        // Display user details in the view
    }

    public function updateUser($id, $data) {
        $userModel = new User();
        $userModel->updateUser($id, $data);
        
        // Redirect to user details page
    }
}
