Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
| 1 | <?php |
||
| 13 | class NotifiableBehavior extends Behavior |
||
| 14 | { |
||
| 15 | public $notifications = []; |
||
| 16 | |||
| 17 | /** |
||
| 18 | * @var Notifier |
||
| 19 | */ |
||
| 20 | public $notifier = 'notifier'; |
||
| 21 | |||
| 22 | public function init() |
||
| 27 | |||
| 28 | /** |
||
| 29 | * @inheritdoc |
||
| 30 | */ |
||
| 31 | public function attach($owner) |
||
| 43 | |||
| 44 | /** |
||
| 45 | * @inheritdoc |
||
| 46 | */ |
||
| 47 | public function detach() |
||
| 61 | |||
| 62 | /** |
||
| 63 | * Handles the event using public properties. |
||
| 64 | * @param Event $event |
||
| 65 | * @throws \InvalidArgumentException |
||
| 66 | * @throws \RuntimeException |
||
| 67 | */ |
||
| 68 | public function handle(Event $event) |
||
| 88 | |||
| 89 | |||
| 90 | } |
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:
