Hello, I have a question--is the note from equazcion here correct? It
is left unchallenged on the page but I can't see how it is correct
since I am under the impression that the environment is refreshed
each page load and the function or method definitions (including
those for session_set_save_handler) would need to be re-established
each page, not each session. I am having tremendous difficulty
debugging some code I wrote and eliminating my uncertainty regarding
this point would be greatly helpful. Any advice would be
appreciated. Thanks!
Because i'm already procrastinating ...

I know this might be obvious, but session_set_save_handler() should
only be called once per session, or else your saved data will keep
getting reset.
If your script doesn't have a predictable start page that will only
be called only once per session, place the session_set_save_handler
statement in an include file, and call it via require_once().
I doubt that this is correct. The save handler that is being set is not,
in itself, a part of the session, but a function that is to be used to
act upon the session. That is, there isn't anything inherent to the
session in the function. Thus, it wouldn't be saved as *a part of* the
session. It's just a handler. It's not as if the function, itself, were
a container for the session vars.
