Yep, wanting to send querystrings to included local PHP files was my
shortcut to calling included files' functions, and supplying them with
parameters. Thinking about it, that might be a tidier solution than
using parent script variables, that appear as globals in the included
script, as parameter containers. I can't guarantee that
REGISTER_GLOBALS will always be enabled, though it appears to be on
the server I'm using, and included file functions may be called more
than once. It seems you only get one shot at running code in the
global scope, when executing it by inclusion from a parent script.
