		0 ignored issues – show Documentation introduced 2015-11-28 10:35 UTC by Report Bug Copy Issue Report `false` is of type `boolean`, but the function expects a `string`. 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.
