But type-cast (object) doesn't know about this restriction: http://3v4l.org/IU3GW . This inconsistency cause some problems. All PHP/5 versions affected including PHP/5.5 and PHP/5.6.0beta3: Some features emits a notice, others aren't. Some features interacts with empty property, others aren't. (there are some different behaviours in very old versions) Test script: --------------- <?php $object = (object) array( "foo" => 42, "" => 37, "bar" => 19, ); echo "+ object created:\n"; var_dump($object); echo "\nenum properties:\n"; foreach ($object as $p => $v) { var_dump($p); } echo "\nget_object_vars()\n"; var_dump(get_object_vars($object)); Expected result: ---------------- Fatal error: Cannot access empty property (or an Exception should be better) Actual result: -------------- + object created: object(stdClass)#1 (3) { ["foo"]=> int(42) Notice: Illegal member variable name in ... on line 9 [""]=> int(37) ["bar"]=> int(19) } enum properties: string(3) "foo" Notice: Illegal member variable name in ... on line 12 string(3) "bar" get_object_vars() Notice: Illegal member variable name in ... on line 17 array(2) { ["foo"]=> int(42) ["bar"]=> int(19) } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67300&edit=1
