How can a PHP session be passed to a different domain on the same server?

To pass a PHP session to a different domain on the same server, you can set the session cookie domain to the root domain using the session_set_cookie_params() function. This will allow the session cookie to be shared across subdomains. Additionally, you can use session_name() to set a consistent session name for both domains. 

// Set session cookie domain to root domain
session_set_cookie_params(0, '/', '.yourdomain.com');
// Set a consistent session name for both domains
session_name('MYSESSION');
// Start the session
session_start();
