반영 클래스 상수(getModifiers)가 반환하는 수정자(Modifiers) 값을 이해하고 싶습니다.
이 메서드는 어떤 종류의 수정자 값을 반환할 수 있고, 그에 대한 예시를 알려주시겠어요?
또한, getModifiers()를 사용한 예제 코드를 부탁드립니다.

    ReflectionClassConstant::getModifiers() 메서드는 클래스 상수의 접근 제한자(modifier)를 반환합니다. 접근 제한자는 클래스 상수가 외부에서 접근할 수 있는 수준을 지정합니다.

    예시로, PHP에서 사용할 수 있는 접근 제한자는 다음과 같습니다.

    - public : 외부에서 접근이 가능합니다.
    - protected : 동일 클래스 또는 상속받은 클래스에서 접근이 가능합니다.
    - private : 동일 클래스 내에서만 접근이 가능합니다.

    getModifiers()를 사용한 예제 코드는 다음과 같습니다.

    #hostingforum.kr
php

class MyClass {

    public const MY_PUBLIC_CONSTANT = 'public';

    protected const MY_PROTECTED_CONSTANT = 'protected';

    private const MY_PRIVATE_CONSTANT = 'private';



    public function testGetModifiers() {

        $reflectionClassConstant = new ReflectionClassConstant('MyClass', 'MY_PUBLIC_CONSTANT');

        echo $reflectionClassConstant->getModifiers() . "n"; // 1 (public)



        $reflectionClassConstant = new ReflectionClassConstant('MyClass', 'MY_PROTECTED_CONSTANT');

        echo $reflectionClassConstant->getModifiers() . "n"; // 2 (protected)



        $reflectionClassConstant = new ReflectionClassConstant('MyClass', 'MY_PRIVATE_CONSTANT');

        echo $reflectionClassConstant->getModifiers() . "n"; // 4 (private)

    }

}


    위 코드에서, ReflectionClassConstant::getModifiers() 메서드는 클래스 상수의 접근 제한자를 반환합니다. 반환되는 값은 다음과 같이 정의됩니다.

    - 1 : public
    - 2 : protected
    - 4 : private
    - 7 : protected & static
    - 8 : private & static
    - 9 : public & static
    - 16 : abstract
