This check looks for function or method calls that always return null and whose return value is used. class A { function getObject() { return null; } } $a = new A(); if ($a->getObject()) { The method `getObject()` can return nothing but null, so it makes no sense to use the return value. The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes. Loading history...
