Yes, Chuck is correct here. The security issue I raised has to do with multiple users on the same shared server, which is how some hosting companies manage their clients. Each user may have a different home directory and has separation from other users, however, usually the same /tmp direct

Hi Dave, After a bit more research, I think I understand why Jochem recommends use of session_save_path() rather than just naming each session differently. The former method provides more security as you can set the location where session cookies are stored. This will help prevent an attacker from
