			0 ignored issues – show Documentation introduced 2019-12-11 20:19 UTC by Report Bug Copy Issue Report `$this->sorting` is of type `string`, but the function expects a `null\|array`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history...
