			0 ignored issues – show Documentation Bug introduced 2019-04-19 00:02 UTC by Report Bug Copy Issue Report It seems like `$this->reflectObject->getDocComment() ?: ''` can also be of type `true`. However, the property `$classDoc` is declared as type `string`. Maybe add an additional type check? Our type inference engine has found a suspicous assignment of a value to a property. This check raises an issue when a value that can be of a mixed type is assigned to a property that is type hinted more strictly. For example, imagine you have a variable `$accountId` that can either hold an Id object or false (if there is no account id yet). Your code now assigns that value to the `id` property of an instance of the `Account` class. This class holds a proper account, so the id value must no longer be false. Either this assignment is in error or a type check should be added for that assignment. class Id { public $id; public function __construct($id) { $this->id = $id; } } class Account { /** @var Id $id */ public $id; } $account_id = false; if (starsAreRight()) { $account_id = new Id(42); } $account = new Account(); if ($account instanceof Id) { $account->id = $account_id; } Loading history...

			0 ignored issues – show Bug introduced 2019-04-19 00:02 UTC by Report Bug Copy Issue Report Are you sure the assignment to `$match` is correct as `static::readClassDocField($this->classDoc)` targeting `suda\orm\struct\TableCla...er::readClassDocField()` 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.

Maybe you did not declare it correctly or list all dependencies? The issue could also be caused by a filter entry in the build configuration.
