1. lifetime: Lifetime of the session cookie, defined in seconds.
2. path: Path on the domain where the cookie will work. Use a single slash ('/') for all paths on the domain.
3. domain: Cookie domain, for example www.example.com. To make cookies visible on all subdomains then the domain must be prefixed with a dot like '.example.com'.
4. secure If TRUE cookie will only be sent over secure connections.
5. httponly: If set to TRUE then PHP will attempt to send the httponly flag when setting the session cookie.
