note 9739 added to Session handling functions

MODIFIED DUE TO 4.02 RELEASE --> the http_*_vars are set , even if they're empty , so i now use empty instead of isset... session handling is really cool. but sometimes , you may need to override the session registered variables with some post or get vars. there is a directive in php.ini (gpc_order) that should do that , but it doesn't for me so i wrote that : (empty($HTTP_POST_VARS))?$postget=$HTTP_GET_VARS:$postget=$HTTP_POST_VARS; while (list($key,$val)=each($postget)){ $$key=$val; } that could be useful.. http://www.php.net/manual/ref.session.php
