How to get a variable name as a string in PHP?

Question

Say i have this PHP code:

$FooBar = \"a string\";

i then need a function like this:

print_var_name($FooBar);

Answer 1

I have this:

  debug_echo(array('$query'=>$query, '$nrUsers'=>$nrUsers, '$hdr'=>$hdr));

I would prefer this:

  debug_echo($query, $nrUsers, $hdr);

The existing function displays a yellow box with a red outline and shows each variable by name and value. The array solution works but is a little convoluted to type when it is needed.

That's my use case and yes, it does have to do with debugging. I agree with those who question its use otherwise.
