Sessions don't work

[Anon]

I am trying to start sessions and i can not get anything to show up in the /tmp folder files when i input this code:

session_start();
session_register("sess_id");

in turns up nothing in the sess_xx34353x(etc.) file.

any ideas why?

It's entirely possible that nothing is written until you actually set the value of $sess_id to something. Try giving it a value and check it again. I'd typically do this:

if(!session_is_registered("sess_id")) {
$sess_id = "ABCDEF";
session_register("sess_id");
}
