안녕하세요~ 코딩하다보니.. 별 거지같은 소스를 만들었는데...
이거나마 도움이 되시라고 소스코드를 올립니다.
참고로 여기서 변수사용은 전역변수 지역변수 여기저기 혼용했는데..
정리할까 생각하다가 그냥 귀찮아서.. 그냥 두었습니다.
그냥 알고리즘 부분만 유심히 보시면 괜찮을 것 같군요.
키값하나만으로도 몇번째 페이지인지.. 리플글은 있는지 다 확인이
되게 만들었거든요.(sql db고치기 귀찮아서.. 그냥 하나로 되게
만듬.. 정말 게을러서리.. //;)
하여간 올립니다요.

눈여겨 봐야할부분은 go()밖에 없습니다. //;
게시물 왕창 늘어나면 루프열라게 돌기때문에 느려질지도 모릅니다. //;
행복하세요~
