Thanks for your reply.
My question was subtly different.
I have no doubt that require_once() will open and include the correct file.
I was concerned about it possibly believing that "/dir1/file.inc" had been
included when it was "/dir2/file.inc". In other words, I was concerned
about the "once" part of it and how it remembers what has already been
included.
My question was about the "once" part of it.
Thanks, Dave.
