PHP：将Cookie域转换为子域

Question

My actual situation

http://www.stackoverflow.com/project1

For this i use this session configuration (the session must be active for up to one hour, and be valid only on the folder /project1 )

$lifetime = 3600;
session_start();
setcookie(session_name(),session_id(),time()+$lifetime,"/project1");

Soon i'll have to move the /project1 in a subdomain

http://project1.stackoverflow.com

How do i change the session to be valid only in the subdomain project1 ? thanks

I suggest you stop managing the Session cookie manually like this, and let PHP handle it automatically for you.

You can set the path, domain, expiry etc for the session cookie with the function session_set_cookie_params
