Re: how can php applications use session control to track multiple users?

There is no need. Sessions are per/computer not global to all. PHP creates a cookie with the session id and stores it on the user's computer. When the session data needs to be reused the cookie is read and the session id retrieved. So what that users sees is the data from their session file and nobody elses. This is all automatic. -Kevin ----- Original Message ----- From: "Wo Chang" <wchang@nist.gov> To: <php-general@lists.php.net> Sent: Friday, August 23, 2002 1:33 PM Subject: [PHP] how can php applications use session control to track multiple users? > Dear Experts, > > I know you can use session_register to register varialbes, > but how do you use sessions for multiple users? > > Ex. > > $valid_user = $username; // let's say $username has "JSmith" > session_register("valid_user"); > > but if another user (SWhite) logins, then the valid_user now > has the value of "SWhite" and the earlier user "JSmith" is > gone.
