PHP: Cookie domain / subdomain control

I have tow page a.php and b.php. I am running my a.php page with the url as http://www.domain.com/a.php. Here, page contains some session values.

Ex: $_SESSION[‘name’]=’my name’;

In b.php i am printing above session value. If i access my b.php page with the url http://www.domain.com/b.php, Session values are working fine.

Ex: echo $_SESSION[‘name’]; //Output ‘my name’;

If i access the same page with the url http://domain.com/b.php , session values are not working.

EX: echo $_SESSION[‘name’]; //No Result

what is the problem and how can i solve this.

Answer 1

You can enable your session on all subdomains with session_set_cookie_params() function

session_set_cookie_params ( 0, '/'  '.domain.com');
