제가 SplSubject 클래스를 사용하여 전역 변수를 공유하는 데 도움이 되고 싶습니다. 하지만 detach() 메서드의 사용법을 이해하지 못하고 있습니다. detach() 메서드는 SplSubject 인스턴스를 분리하는 데 사용되나요? 분리된 후에는 어떤 변화가 있나요?

    SplSubject 클래스는 SplObserver 인터페이스를 구현한 클래스입니다. detach() 메서드는 SplObserver 인스턴스를 SplSubject 인스턴에서 분리하는 데 사용됩니다.

    예를 들어, 다음 코드를 살펴보겠습니다.

    ```php
    class MyObserver implements SplObserver {
    public function update(SplSubject $subject) {
    echo "Observer: Updated with data: " . $subject->getData() . "\n";
    }
    }

    $subject = new SplSubject();
    $observer = new MyObserver();

    // Observer를 Subject에 등록합니다.
    $subject->attach($observer);

    // Subject에 데이터를 추가합니다.
    $subject->attach($observer);
    $subject->attach($observer);
    $subject->attach($observer);
    $subject->attach($observer);
    $subject->attach($observer);
