note 101789 added to function.session-regenerate-id

@ Ben Johnson Your code works, but why are you doing so much more effort. <?php // initialize session data based on new or existing session id session_start(); // get a new session id and delete the old associated session file (which is linked with the old session id) session_regenerate_id(true); // free all variables in $_SESSION, the $_SESSION in the current script still exists, but the associated session file is gone. The data in $_SESSION can not be retrieved anymore from the filesystem. session_unset(); ?> What we have here is: A empty $_SESSION superglobal A new id and a new associated session file The old session associated file is deleted so if you change your session id to the old one and initialize the data with session_start(), it just creates a new session associated file ---- Server IP: 69.147.83.197 Probable Submitter: 178.202.57.61 ---- Manual Page -- http://www.php.net/manual/en/function.session-regenerate-id.php Edit -- https://master.php.net/note/edit/101789 Del: integrated -- https://master.php.net/note/delete/101789/integrated Del: useless -- https://master.php.net/note/delete/101789/useless Del: bad code -- https://master.php.net/note/delete/101789/bad+code Del: spam -- https://master.php.net/note/delete/101789/spam Del: non-english -- https://master.php.net/note/delete/101789/non-english Del: in docs -- https://master.php.net/note/delete/101789/in+docs Del: other reasons-- https://master.php.net/note/delete/101789 Reject -- https://master.php.net/note/reject/101789 Search -- https://master.php.net/manage/user-notes.php
