same session across different subdomains

[future-architect]

How do I create a session so that it will work across different subdomains on my website?

I think you are going to have to store that information as a cookie if it will be used in sessions across mulitple domains.

Add this before you start your session:

ini_set("session.cookie_domain", ".your_domain.com");

This will allow session variables travel trough your subdomains.

You can also change your php.ini file but it will affect the whole server permanently.
