Previous Comments: ------------------------------------------------------------------------ [2012-03-30 10:01:07] yohgaki@php.net I'll implement by checking hash of serialized session data. 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
