No.

And there cannot be, as any given variable could have multiple
references and be passed around through several functions, getting a
different name each time.

You probably should be putting 'foo' and 'abc' into an array instead.

$foobar['foo'] = 'abc';

You can then address 'foo' and 'abc' with various array functions.

no - and if you think you need this then there is something very wrong with you 
code,
it's completely backward-assed and you need to rethink what you are doing.

maybe if you explain the exact nature of your problem we could show you
a better way of tackling it so that you are no longer in need of a function
that 'tells you the name of the varable'

 
 Thanks

I found this on the zend forums. Hope it helps.

function Dump($var) {
if (key_exists($var, $GLOBALS)) {
echo pre$$var:\n;
var_dump($GLOBALS[$var]);
echo \n/pre\n;
}
else
echo span class='error'No variables named 
em$$var/em!/span\n;
}
