			1 ignored issue – show Bug introduced 2016-09-19 04:30 UTC by Report Bug Copy Issue Report It seems like you code against a specific sub-type and not the parent class `CI_Model` as the method `__construct()` does only exist in the following sub-classes of `CI_Model`: `Auth_Model`, `Batoto`, `DynastyScans`, `History_Model`, `KireiCake`, `KissManga`, `MangaFox`, `MangaHere`, `MangaPanda`, `MangaStream`, `Site_Model`, `Sites_Model`, `Tracker_Model`, `User_Model`, `User_Options_Model`, `WebToons`. Maybe you want to `instanceof` check for one of these explicitly? Let’s take a look at an example: abstract class User { /** @return string / abstract public function getPassword(); } class MyUser extends User { public function getPassword() { // return something } public function getDisplayName() { // return some name. } } class AuthSystem { public function authenticate(User $user) { $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName())); // do something. } } In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different sub-classes of User which does not have a getDisplayName() method, the code will break. Available Fixes Change the type-hint for the parameter: class AuthSystem { public function authenticate(MyUser $user) { / ... / } } Add an additional type-check: class AuthSystem { public function authenticate(User $user) { if ($user instanceof MyUser) { $this->logger->info(/* ... /); } // or alternatively if ( ! $user instanceof MyUser) { throw new \LogicException( '$user must be an instance of MyUser, ' .'other instances are not supported.' ); } } } Note:* PHP Analyzer uses reverse abstract interpretation to narrow down the types inside the if block in such a case. Add the method to the parent class: abstract class User { /** @return string / abstract public function getPassword(); /* @return string */ abstract public function getDisplayName(); } Loading history...
