ok here is the problem
i am creating a Content managment sysytem for a client, however, i have found out that their webhost does not support Session control. long story short, here is their reply to my question i sent to help desk.
servers do not support file based sessions. Writing to /tmp
on the webserver is not permitted. The reason for that is: we have a
web
cluster, where the load of the file server is balanced by three
webserver machines. This means that you cannot save a session into a
file in /tmp on one server, as there is no guarantee that you will stay
on the same server, when another request is made.
Workaround:
Use database session handler instead. To implement database storage,
you
will need to use session_set_save_handler() to create a set of
user-level storage functions.
ok
What do they mean? what is a database session, and how do they work? what is the code to make them work
what is the
session_set_save_handler()
and how do i use it?
