note 78428 added to function.session-set-save-handler

I think it is very important here to stress that the WRITE method should use UPDATE+INSERT (or mysql specific REPLACE). There is example code "out there" that uses just UPDATE for the write method, in which case, when session_regenerate_id is called, session data is lost (as an update would fail, as the key has changed). I've just wasted a whole day due to this (I know I should have thought it through / RTFM, but it is an easy trap to fall into). ---- Server IP: 87.124.64.96 Probable Submitter: 193.128.117.15 ---- Manual Page -- http://www.php.net/manual/en/function.session-set-save-handler.php Edit -- https://master.php.net/note/edit/78428 Del: integrated -- https://master.php.net/note/delete/78428/integrated Del: useless -- https://master.php.net/note/delete/78428/useless Del: bad code -- https://master.php.net/note/delete/78428/bad+code Del: spam -- https://master.php.net/note/delete/78428/spam Del: non-english -- https://master.php.net/note/delete/78428/non-english Del: in docs -- https://master.php.net/note/delete/78428/in+docs Del: other reasons-- https://master.php.net/note/delete/78428 Reject -- https://master.php.net/note/reject/78428 Search -- https://master.php.net/manage/user-notes.php
