		0 ignored issues – show Bug introduced 2019-03-05 23:44 UTC by Report Bug Copy Issue Report Are you sure the assignment to `$primary` is correct as `$this->getRelativePixelC...property, $reflections)` targeting `Smindel\GIS\Service\Tile...ativePixelCoordinates()` seems to always return null. This check looks for function or method calls that always return null and whose return value is assigned to a variable. class A { function getObject() { return null; } } $a = new A(); $object = $a->getObject(); The method `getObject()` can return nothing but null, so it makes no sense to assign that value to a variable. The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes. Loading history...
