여기가 소스끝..
배포하고 있는 ajax 채팅소스가 있는데,
그건 채팅방 개설해서 사용하는 방식이고,
이건 채팅방 하나짜리 입니다.
이건 따로 파일로 배포할게 아니라서, 이렇게 개인블로그에 올렸는데,
여기도 올려봅니다.

브라우저에서 인코딩은 euc-kr
소스내부 처리과정의 인코딩은 utf-8입니다.
채팅 데이타는 텍스트파일 25개에 순차적으로 저장됩니다.
26번째는 다시 01번 파일에,,,(그렇게 로테이션으로..)

어디까지 읽어갔는지를 사용자마다 서버에 파일로 기록하고 있습니다.(파일이름에다가)
사용자가 갱신해서 읽어간 방문자목록의 시간을 파악하기 위해서,
방문자목록을 읽어갈때, 빈파일을 생성하도록 해서,, 그 파일의 생성시점을 기준으로해서,
방문자목록에 변동이 있을때, 다시 읽어가거나, 아니면 지나치거나 합니다.

서버로의 접속은 ajax로 이뤄지고, 접속이 끝나고 1.5초 뒤에 다시 접속합니다.
배포하고 있는, 채팅방 개설하는 소스에는, 파일업로드도 있는데,
이건 간결하게 하느라고, 파일업로드는 없앴습니다.

관리자의 확인은, mysql에 접속되는지 여부로 판단합니다.
mysql을 그외의 용도로는 사용하지 않습니다.

사용된 php함수중에 glob() 함수가 있는데,
이건 PHP 4.3.0 버전이후부터 된다고 하더군요.
그래서, PHP 4.3.0 버전부터 됩니다.

소스10번줄, 11번줄은 소스의 파일이름과 데이타저장경로를 설정하는 부분입니다.
$chat = "chat.php"; //파일이름
$folder = "./"; //데이타파일 저장경로(권한777)

경로나 이름은 어떻게 해도 좋은데,
반드시 $chat 변수에 파일이름을 담고, $folder 변수에 ,,php가 읽고쓰고 할수 있도록, 권한 777을 준 디렉토리를 지정해줘야 합니다.

27~28번줄은 사용자를 특정하는 부분입니다.
//$ip = str_pad(str_replace('.','',$_SERVER[REMOTE_ADDR]),12,'x');
$ip = substr($sessid,0,12);

아이피를 이용하고자 하면 위쪽에 주석을 제거하고, 아래쪽에 주석처리하시고,
28줄에 $sessid는 그 위쪽에서 session_id()를 담고 있는 변수입니다.
세션아이디로 사용자를 특정하고자 할때는 지금 그대로.... 사용하면 됩니다.

귓속말기능 있고, 글자색같은..간단한 태그지원기능이 있고,
관리자에 의한 강퇴도있고, 채팅방 리셋도 있고, 금칙어설정도 있고, 금지닉네임설정도 있습니다.

 
배포하고 있는 채팅소스는 http://www2.ssam.biz/blog/?tb=1&ct=6 여기서..
