How do I implement the repository pattern in PHP?

The repository pattern is a design pattern that provides an abstraction layer between the data access and the business logic. To implement it in PHP, you can start by creating an interface for your repository.

What should the interface include?

The interface should define methods for common operations like find, findAll, save, and delete. This ensures that any class implementing the repository will have these methods.

Can you give me an example of a repository class?

Sure! Here's a simple example:

class UserRepository implements UserRepositoryInterface {
    protected $db;

    public function __construct(Database $db) {
        $this->db = $db;
    }

    public function find($id) {
        // logic to find a user by ID
    }

    public function save(User $user) {
        // logic to save a user
    }
}

What are the benefits of using the repository pattern?

The repository pattern promotes separation of concerns, makes unit testing easier, and provides a more organized way to manage data access.
