			0 ignored issues – show Bug introduced 2017-12-17 13:02 UTC by Report Bug Copy Issue Report Are you sure the usage of `$shardManager->getCurrentDistributionValue()` targeting `Doctrine\DBAL\Sharding\P...rentDistributionValue()` seems to always return null. 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...
