Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php We decided to do less strict checking on the constructor. So this is the way it is meant to be. Previous Comments: ------------------------------------------------------------------------ [2009-05-24 17:14:07] kev dot simpson at gmail dot com Description: ------------ Tested in 5.2.5, 5.2.9-2 and 6.0.0-dev using Apache 5.0.59 When a class uses a private scope on a method, any grandchild class can demote the scope regardless of what the primary class's immediate child scope is. Curious if I can exploit this as a feature or if it is indeed a bug. Example is in order to help visualize. Reproduce code: --------------- <?php class TestParent { private function __construct() { } } class Child extends TestParent { public function __construct() // Ok, parent is private and unviewable, so not technically overridding { printf("%s\n", __CLASS__); } } class GrandChild extends Child { protected function __construct() // Override here; scope reduction is prohibited in PHP { parent::__construct(); printf("%s\n", __CLASS__); } public static function createInstance() { return new self; } } GrandChild::createInstance(); ?> Expected result: ---------------- I expect this to produce a fatal error indicating that 'Access level to GrandChild::__construct() must be public (as in Child) in ....' Actual result: -------------- Child GrandChild Returning of object of instance GrandChild. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48376&edit=1
