Short description

Factories help when creation logic is non-trivial or when you want to return interface types.

Simple factory

class NotifierFactory {
    public static function make(string $channel): Notifier {
        return match ($channel) {
            'email' => new EmailNotifier(),
            'sms' => new SmsNotifier(),
            default => throw new InvalidArgumentException('Unknown channel'),
        };
    }
}
