RE: [PHP] Environment Variables -- HTTP_REFERER

Well an ad hoc method is to immediately start a session when the user visits a page and then insert the following into a db the following. 1. SID or session_id() 2. current host and page $_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'] Evertime they visit a page you update their record w/ the current page, if you need the last page, you pull it out of the db before you update it. You can pull the last page they were at by pulling page out of the db that matches their SID (and/or TIMESTAMP if you want). Periodically though you will need to run a script and delete old SID's as your db will get big fast. Ad hoc but works. -Peter > -----Original Message----- > From: Darwin [mailto:superbus22@attbi.com] > Sent: Thursday, October 24, 2002 06:34 > To: php-general@lists.php.net > Subject: [PHP] Environment Variables -- HTTP_REFERER > > > Hello, > > I am running PHP 4.0.6 in a Windows XP environment.
