Namely, objects are not deep-copied on assignment. This may cause substantial problems to legacy applications that rely on the compatibility mode. Reproduce code: --------------- $a->y->z = 0; $b = $a; // should perform deep copy of $a $b->y->z = 1; // hence this should have no effect on $a var_dump($a); Expected result: ---------------- object(stdClass)#1 (1) { ["y"]=> object(stdClass)#2 (1) { ["z"]=> int(0) // <-- } } Actual result: -------------- object(stdClass)#1 (1) { ["y"]=> object(stdClass)#2 (1) { ["z"]=> int(1) // because $a->y and $b->y are still one object after the assignment } } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33243&edit=1
