Here is a simple function which checks for reference, and works with objects by the test I did. 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 $res; } ?> --was-- This version of the function is much more compact but works the same way. Have now fully checked under PHP version 5.2+ and can confirm that it works for everything I could think of, including objects. <?php function is_reference_to(&$a, &$b) { if ($a !== $b) return false; //Important. $temp = $a; $a = ($a === null) ? "" : null; $res = ($b === $a); $a = $temp; return $res; } ?> http://php.net/manual/en/language.references.spot.php
