And you probably don't want this either, because $a and $b might actually point to the same value (e.g. due to compiler optimization) For objects you could use the equality operator (===).

Short example: $a = 5; $b = 5; $a_ref1 = &$a; $a_ref2 = &$a; $b_ref = &$b; PHP needs a function (or operator) which will return TRUE, when comparing $a_ref1 and $a_ref2, but FALSE, if comparing $a_ref1 and $b_ref. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=15232&edit=1
