note 48789 added to function.session-regenerate-id

By inspecting the source code, I am not sure that after session_regenerate_id() run, the original session data does not destroy (still keeps at the system) that sniffers still hijack by applying original session identifier. In addition, I find that if user-level session storage handler is used. session_regenerate_id() does not work. ---- Manual Page -- http://www.php.net/manual/en/function.session-regenerate-id.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+48789 Delete -- http://master.php.net/manage/user-notes.php?action=delete+48789&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+48789&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+48789&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+48789&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+48789&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+48789&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+48789&report=yes Search -- http://master.php.net/manage/user-notes.php
