Referencing the same thing?

[Anon]

Is there any way to tell if two variables reference the same thing? i.e

$a = "something";
$b =& $a;
if same_reference($a, $b) { do something; }

Or is there a ==& comparison operator?
Major need for something like this.

if ($a == $b)
{
echo "Variable A is the same as Variable B";
}

possibly?

No, no, no, no, no. No!

That tests if they have the same value. I know how to do that. I want to test if they are the same variable, if they have the same reference.

Assume it's a function called samevar. Then in this case:

$a = 1;
$b = 2;
echo samevar($a, $b)

would output false but

$a = 1;
$b =& $a;
echo samevar($a, $b)

would output true. See?
