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

So, how do you make the sessions looks like: > >JSmith|s:6:"JSmith";SWhite|s:6:"SWhite"; > >Is this the way how people usually implment to track multiple >users? No, no, no, no, no. :-) The entire *POINT* of session variables is to keep JSmith and SWhite *separate* When JSmith gets *their* session_register('valid_user') they get a Cookie sent to their browser. When SWhite gets *their* session_register('valid_user') they get a *different* Cookie. When either one of them comes back, their browser presents the Cookie, and PHP "knows" which one is JSmith and which one is SWhite because they have different Cookies. If this is all giving you a big headache, you could just say "It's magic" and go on with life :-) But PHP is not going to "mix" two users together. -- Like Music? http://l-i-e.com/artists.htm
