Variables in a session in PHP3

[Anon]

Hi,

I wonder if it is possible to have some variables which are constant throughout a session in PhP3. I understand that PHP4 does it, but I only have access to 3.

Specifically, I am trying to set up a user authetication system without using the standard dialog box. I was trying to assign values directly to $PHP_AUTH_USER and $PHP_AUTH_PW which I think are constant across a session. But this does not seem to work. The variables are only set in the current page, not on any successive page loads.

Also, I don't want to use cookies since some people might have them turned off.

Thanks,

Marc
