No there is not, because an included file *executes* at the time it is

Include files are libraries. They are not functions. What you're
looking for
is a function. Don't try to use include files as functions. Therein

pain.
I have function definitions in included files all over the place. I do that
so one file will not be too big to keep scrolling back and forth through
to develop and debug. These are mainly in conjunction with multi
phase self processing forms.
Variables I could guess would be overwritten,
but if I have a function fu defined in two different files that are include
in, say, a loop and I want to call one function fu on one iteration from
one included file, then the next iteration I include the next file and
call fu that is a different version, which function would be executed on
the second iteration?
You can't have two functions with the same name for exactly this reason.
$ php -a
Interactive mode enabled
<?php
function a() { echo "1\n"; }
function a() { echo "2\n"; }
[ CTRL-D ]
Fatal error: Cannot redeclare a() (previously declared in -:2) in - on
line 3
So when script '2' is included (ie the 2nd loop), it's going to throw
this sort of error.
Time to rethink your design.
