[Techtalk] PHP, session variables & cookies

[Sue Stones]

I am looking into the legal implications of the website that I have just 
written, (reminderanywhere.com) and working on a privacy statement. 
(Well I'm not doing much of the work on the privacy statement, I made my 
partner do it).

But the issue has come up of whether we are using cookies.  I have kept 
track of the user id using a session variable.  But I don't know 
anything about how session variables work, and whether that involves 
using cookies to keep track of the session.  Does anyone understand the 
internals of PHP in the regard?

thanks
