Allow php sessions to carry over to subdomains?

Question

Hello I use php sessions (not cookies, except for session id cookie) for all user data, and when a user goes to their profile user.mydomain.com they are immediately "logged out" untill then remove the subdomain.

Is there a way to accept sessions from all domains as long as its *.mydomain.com

thanks!

Answer 1

Here are 3 options.

Place this in your php.ini:

session.cookie_domain = ".example.com"

In your .htaccess:

php_value session.cookie_domain .example.com

As the first thing in your script:

ini_set('session.cookie_domain', '.example.com' );
