for destroying the session without closing the browser it should work... <?php session_start(); $_SESSION = array(); session_destroy(); $userid = safehtml($_POST['userid']); session_start(); //$sessionid can be used to retrieve the current name and session id as a string $sessionid=session_id(); //userid can be re-used as a variable in other php files session_register("userid"); After leaving the page and coming back, without closing the browser, and performing a SQL sentence like "insert into user_table values ('$userid','$sessionid')"; I get sessionid is still the same!! why¿? thanks, Pere -- View this message in context: http://www.nabble.com/an-easy-destroying-session-issue...-tp16447090p16447090.html Sent from the PHP - General mailing list archive at Nabble.com. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
