What are the best practices for implementing the Repository Pattern in PHP?

The Repository Pattern is a design pattern that helps separate the data access logic from the business logic in an application, making it easier to maintain and test. To implement the Repository Pattern in PHP, you can create a separate class for each entity in your application that handles all the database operations related to that entity. 

<?php

interface UserRepositoryInterface {
    public function getById($id);
    public function getAll();
    public function save(User $user);
    public function delete(User $user);
}

class UserRepository implements UserRepositoryInterface {
    public function getById($id) {
        // implementation
    }

    public function getAll() {
        // implementation
    }

    public function save(User $user) {
        // implementation
    }

    public function delete(User $user) {
        // implementation
    }
}

class User {
    // properties and methods
}

$userRepository = new UserRepository();
$user = new User();

$userRepository->save($user);
