No can do. Please have a in-depth look at the PHP manual,
chapter "References to variables".

I'll try to show you the inability to know the *name* of a variable. And,
please, before replying, do RTFM.

<?php

$a = "foobar";
$b =& $a;
$c =& $a;
$d =& $a;

unset($a);

echo some_function($c); // WTF??

?>

Now, in your opinion, what should this return?? $b, $c and $d all point to
the same memory address, because of how references work. And the name $a,
which originated that memory address, does not exist. So, do we
return 'b', 'c' or 'd'??
