What are the benefits of separating responsibilities between different classes in PHP, such as having the Spiel-Klasse handle game functionalities and the Welt-Klasse act as a player repository?

Separating responsibilities between different classes in PHP helps to improve the organization and maintainability of the code. By having the Spiel-Klasse handle game functionalities and the Welt-Klasse act as a player repository, it allows for better code reusability, easier debugging, and a more modular approach to development.

class Spiel {
    public function startGame() {
        // Game functionalities
    }
}

class Welt {
    public function getPlayer($id) {
        // Retrieve player from repository
    }

    public function savePlayer($player) {
        // Save player to repository
    }
}
