What the PHP.ini entry should look like

I've never done this myself, and my host is running me around with this answer. Basically I can't perform sessions because they can't write to /tmp. Well apparently /tmp doesn't exist, but /temp does. They told me to put session_save_path("c:/temp"); at the start of all my sessions, then said if I could find out what the PHP.ini entry for that line should look like, they would edit it for me. So what I'd like is to change that session_save_path from c:/tmp to c:/temp Is there just a line in the ini that says just that? I can't believe it would be that difficult, but I'd like to hear from someone who's done this before I give a reply. Thanks, Pete
