Because PHP passes arguments by value, you will be out of luck in most
cases -- by the time your debugging function sees the argument, it's no
longer tied to the calling scope. Michael Sims' example function works
only for variables in the global scope, which probably won't work for
anything complex enough to need its own debugging library.

You may find what you need in debug_backtrace(). Alternatively, just pass
the variable name along:
function echo_var($varname, $varvalue) {
printf("%s: %s\n", $varname, $varvalue);
}
...Which isn't much of an improvement over a plain old echo/print. And if
that's good enough for Brian Kernighan, I'd hope it's good enough for you.
