저도 배우는 입장이라 정확한 답변을 달긴 어렵지만 제 홈페이지 포인트 순위에 회원권한에 따라 회원 등급을 나누게 되어있거든요. 가령 준회원 정회원 이렇게...

이부분을 응용하면 가능하리라 생각되네요.
일단 해당 소스는 이렇습니다.

$g4[title] = "" . $html_title;

// 접근 권한 검사(내 스타일)
if (!$member[mb_id]) {

    alert("회원이 아니시면 포인트 순위를 볼 수 없습니다..\\n로그인을 해주세요.\\n");

성공하시길 ㅜㅜ

단순히 숫자를 한글로 변환하실려면 간단히 IF문을 사용하시면 되겠네용.

IF(이숫자가 들어오면)
{한글로바꿔서 출력}

이런식으로요. 스위치문으로 사용해도 될거같네요.
