note 102307 added to language.references.spot

This version of the function is much more compact but works the same way. Have now fully checked under PHP version 5.2+ and can confirm that it works for everything I could think of, including objects. 

<?php

function is_reference_to(&$a, &$b)
{
	if ($a !== $b)
		return false; //Important.
	
	$temp = $a;
	$a = ($a === null) ? "" : null;
	$res = ($b === $a);
	$a = $temp;
	return $res;
}

?>
