			0 ignored issues – show Documentation introduced 2018-08-08 09:10 UTC by Report Bug Copy Issue Report `$this->runCompletion()` is of type `array<integer,string>`, but the function expects a `string\|object<Symfony\Co...onsole\Output\iterable>`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history...
