		0 ignored issues – show Compatibility introduced 2016-08-05 07:56 UTC by Report Bug Copy Issue Report `$user` of type `object<Illuminate\Contracts\Auth\Authenticatable>` is not a sub-type of `object<Tinyissue\Model\User>`. It seems like you assume a concrete implementation of the interface `Illuminate\Contracts\Auth\Authenticatable` to be always present. This check looks for parameters that are defined as one type in their type hint or doc comment but seem to be used as a narrower type, i.e an implementation of an interface or a subclass. Consider changing the type of the parameter or doing an instanceof check before assuming your parameter is of the expected type. Loading history... Documentation introduced 2016-08-05 07:56 UTC by Report Bug Copy Issue Report `$request->route()` is of type `object\|string`, but the function expects a `object<Illuminate\Routing\Route>`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history...
