			0 ignored issues – show Bug introduced 2024-10-31 18:42 UTC by Report Bug Copy Issue Report Are you sure the assignment to `$di` is correct as `Phalcon\Di\Di::getDefault()` targeting `Phalcon\Di\Di::getDefault()` 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...
