What I was thinking with debug_backtrace() is that you could get the
information for the function that called the function you want the
variable name for, *reducing* the likelyhood of duplicate values, but
admitedly not eliminating it.
You could also pass the name of the variable to the function:
someFunction($foo, $varName=""){ print $varName; }
call it with -> someFunction($bar, 'bar');
That would definately get you what you want, but again it would be messy
to look at.
