It seems like you assume a child class of the class `Illuminate\Database\Connection` 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 2019-04-24 19:07 UTC by Report Bug Copy Issue Report `$connection->getPostProcessor()` is of type `object<Illuminate\Databa...y\Processors\Processor>`, but the function expects a `null\|object<lroman242\La...sandra\Query\Processor>`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history...

If you return a value from a function or method, it should be a sub-type of the type that is given by the parent type f.e. an interface, or abstract method.

This principle also belongs to the SOLID principles for object oriented design.

The base class `Post` returns a simple string and outputting a simple string will work just fine. However, the child class `BlogPost` which is a sub-type of `Post` instead decided to return an `object`, and is therefore violating the SOLID principles. If a `BlogPost` were passed to `my_function`, PHP would not complain, but ultimately fail when executing the `strtoupper` call in its body. Loading history...
