Edit report at https://bugs.php.net/bug.php?id=17860&edit=1 ID: 17860 Comment by: bouvrette dot nicolas at gmail dot com Reported by: Xuefer at 21cn dot com Summary: Suggestion: auto detect whether session changed Status: Closed Type: Feature/Change Request Package: Session related Operating System: all PHP Version: 4.2.1 Assigned To: yohgaki Block user comment: N Private report: N New Comment: Is there any configuration so avoid this new behavior? I myself manage the session expiration in the DB and need that every page load force a write even if nothing has changed. I checked here and couldn't find anything about this new feature: http://php.net/manual/en/session.configuration.php This is breaking my code right now... could we implement a way to configure this?

Saving unneeded session writes is good for many apps. ------------------------------------------------------------------------ [2002-06-20 00:15:11] Xuefer at 21cn dot com yes, i know, a file handler don't need to update mtime, they have "atime", but for a drive which not local, or sql_session_handler, a remote sql server, it's nightmare to send session data every page load we need to detect whether "it's REALLY need to update session data" ------------------------------------------------------------------------ [2002-06-20 00:09:15] Xuefer at 21cn dot com session data changed need ===> session update session active need only ===> session "mtime" update, and don't need to update frequently sometime, it's hard for ourself do judge whether to open a session in readonly mode. it is possible to detect whether $_SESSION is changed ? i just do it using md5 now, but if there's and capability to do internally, e.g.: a flag set when session changed, should be faster than md5. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=17860&edit=1
