Here is some info about how to use SID. Experiment run on WAMPserver, PHP version 5.2.6.
Using FireFox 3.0.
In php.ini, session.use_cookies has an effect upon whether or not SID passes an empty string or the session info. If it is on, SID is evaluated for the session info upon initial page view, but once a cookie has been set (automatically by session.use_cookies) in the browser, subsequent views (like page reloads or using the back button) have the cookie being returned to the script so SID is then evaluated as an empty string. On the other hand, if session.use_cookies is off, (and provided you don't create a cookie by some other means), SID will evaluate as the session info no matter how many times you reload the page or use the back button because session_start() keeps opening a new session and no cookies are being set. Be aware this behavior will change the functionality of any links you build with SID. To have a reliable link with session info in it, spell it out using session_name() and session_id(), not SID. Example:
echo '<a href="page2.php?' . session_name() . ' =' . session_id() . ' ">page2</a>' ;
and not
echo '<a href="page2.php?' . SID . ' ">page2</a>';
Two other settings that I thought might be relevant were not. session.use_only_cookies and session.use_trans_sid have no effect at all on the evaluation of SID for a specific line in the code, that is, in regard to whether or not it is evaluated as an empty string or as the session info.
And as to functioning in your code, using both session.use_trans_sid and also successfully evaluating SID for session info (as described above) will create a doubling of the session info, screwing up the path you are trying to create.
예약 상수
이 확장은 다음의 상수들을 정의합니다. 이 확장을 PHP에 내장했거나, 실행시에 동적으로 읽어들일 경우에만 사용할 수 있습니다.
- SID (string)
- "name=ID" 형식으로 세션명과 세션 ID를 가지거나, 세션 ID가 고유한 세션 쿠키로 설정되었을 경우엔 빈 문자열을 가지는 상수입니다. ID는 session_id()에서 반환하는 것과 동일한 id입니다.
