How can the concept of a "Gott-Objekt" be avoided when designing PHP classes for database interactions?

To avoid the concept of a "Gott-Objekt" (God object) when designing PHP classes for database interactions, it is important to adhere to the principles of object-oriented programming and separation of concerns. This means creating separate classes for database connection, data manipulation, and business logic, rather than combining all functionality into a single class. By breaking down the responsibilities of each class and utilizing dependency injection, you can create a more modular and maintainable codebase. 

// Example of separating concerns in PHP classes for database interactions

// Database connection class
class DatabaseConnection {
    private $host;
    private $username;
    private $password;
    private $database;

    public function __construct($host, $username, $password, $database) {
        // Initialize database connection parameters
        $this->host = $host;
        $this->username = $username;
        $this->password = $password;
        $this->database = $database;
    }

    public function connect() {
        // Implement database connection logic here
    }
}

// Data manipulation class
class DataManipulation {
    private $dbConnection;

    public function __construct(DatabaseConnection $dbConnection) {
        // Inject database connection dependency
        $this->dbConnection = $dbConnection;
    }

    public function fetchData() {
        // Implement data retrieval logic here
    }

    public function saveData($data) {
        // Implement data insertion logic here
    }
}

// Business logic class
class BusinessLogic {
    private $dataManipulation;

    public function __construct(DataManipulation $dataManipulation) {
        // Inject data manipulation dependency
        $this->dataManipulation = $dataManipulation;
    }

    public function processBusinessLogic() {
        // Implement business logic using data manipulation methods
    }
}
