I think the problem is that by the time you've included the file, the 
overwriting of your defined vars has already occurred.

One thing you can try is including it in a dummy file, and at the bottom 
of the file call get_defined_vars(), get_defined_constants(), and 
get_defined_functions(). Output the returned arrays with var_dump or 
print_r and then compare the outputs of two different included files. I 
don't think this would catch the case of functions that, when called, 
declare global vars or constants but if they do that they deserve to 
fail anyway. :) For OO code you'd have to use the analogous functions 
that were already mentioned in this thread.

Just a thought.
