		0 ignored issues – show Bug introduced 2015-12-30 17:36 UTC by Report Bug Copy Issue Report Are you sure the assignment to `$annotationObject` is correct as `$this->reader->getProper...ectionProperty, $class)` (which targets `Doctrine\Common\Annotati...getPropertyAnnotation()`) 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...

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...
