It's true that your variable could/would/should appear in debug_backtrace,
but how would you pick it out from all the other variables that would
appear in your debug_backtrace?

For that matter, it's in $_GLOBALS, but how would you pick it out?

You could print out all variables that were equal to your variable, and
have a list of candidates...

<?php
  $x = 5;
  $y = 3;
  $z = 5;
  while (list($k, $v) = each($GLOBALS)){
    if ($v === $x) echo "$k might be your variable...<br />\n";
  }
?>


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.
