i tried it already with a stored password + user ID. in a global
variable, and guess what: they're not visible. but only in the function
listing(). in the function start() they are both visible...

i have a feeling it's more complex than that. a script calls itself,
rebuilds HTML code. has the script ended or not? the script that did
the call has ended. but since it has called itself, it hasn't. i find
these recursion matters a bit vague when it comes to scipts that
generate themselves.

i don't think that would be a problem, as long as you explicitely do a
begin /end transaction.
i tried the original script in a more unmodified way (it comes from the
latest Dutch issue of C't magazine), but it has the same problem. this
made me think that the problem is maybe in some setting in php.ini or
httpd.conf. i'm going to do a complete reinstall of apache and php. if
the problem persists, i will try to make the script as small as
possible while still illustrating the problem.
so, maybe until later, and thanks for your reaction.
