note 101789 deleted from function.session-regenerate-id by danbrown

Note Submitter: sietse dot au at gmail dot com ---- @ 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
