			0 ignored issues – show Documentation Bug introduced 2020-02-18 21:33 UTC by Report Bug Copy Issue Report `$doctrine` is of type `object<Doctrine\Persistence\ManagerRegistry>`, but the property `$doctrine` was declared to be of type `object<Doctrine\Bundle\DoctrineBundle\Registry>`. Are you sure that you always receive this specific sub-class here, or does it make sense to add an `instanceof` check? Our type inference engine has found a suspicous assignment of a value to a property. This check raises an issue when a value that can be of a given class or a super-class is assigned to a property that is type hinted more strictly. Either this assignment is in error or an instanceof check should be added for that assignment. class Alien {} class Dalek extends Alien {} class Plot { /** @var Dalek */ public $villain; } $alien = new Alien(); $plot = new Plot(); if ($alien instanceof Dalek) { $plot->villain = $alien; } Loading history...

			0 ignored issues – show Bug introduced 2015-11-22 19:11 UTC by Report Bug Copy Issue Report It seems like you code against a concrete implementation and not the interface `Sonata\NotificationBundl...essageIteratorInterface` as the method `isBufferEmpty()` does only exist in the following implementations of said interface: `Sonata\NotificationBundl...rroneousMessageIterator`, `Sonata\NotificationBundl...eManagerMessageIterator`, `Sonata\NotificationBundl...eManagerMessageIterator`. Let’s take a look at an example: interface User { /** @return string / public function getPassword(); } class MyUser implements 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 implementation 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 interface: interface User { /** @return string / public function getPassword(); /* @return string */ public function getDisplayName(); } Loading history...
