		0 ignored issues – show Documentation Bug introduced 2017-06-18 23:57 UTC by Report Bug Copy Issue Report It seems like `$parent` can also be of type `object<self>`. However, the property `$parent` is declared as type `object<BitWasp\Bitcoin\S...\Path\LogicOpNode>\|null`. 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 Documentation introduced 2017-06-18 23:57 UTC by Report Bug Copy Issue Report `$this` is of type `this<BitWasp\Bitcoin\Script\Path\LogicOpNode>`, but the function expects a `null\|object<self>`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history...
