			0 ignored issues – show Documentation Bug introduced 2016-03-05 14:01 UTC by Report Bug Copy Issue Report `$locator` is of type `object<Zend\ServiceManag...erviceLocatorInterface>`, but the property `$serviceLocator` was declared to be of type `object<Zend\ServiceManager\ServiceManager>`. 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...
