 * messages to specific destination defined by the target, such as emails, files.
 *
 * Level filter and category filter are combinatorial, i.e., only messages

 * @property bool $enabled Whether to enable this log target. Defaults to true.

 * For more details and usage information on Target, see the [guide article on logging & targets](guide:runtime-logging).

However, the property `$_enabled` is declared as type `boolean`. Maybe add an additional type check? Our type inference engine has found a suspicous assignment of a value to a property. This check raises an issue when a value that can be of a mixed type is assigned to a property that is type hinted more strictly. For example, imagine you have a variable `$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...
