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 |
||
| 9 | class ActionForm { |
||
| 10 | |||
| 11 | /** @var array */ |
||
| 12 | private $model; |
||
| 13 | |||
| 14 | /** @var array|Element[] */ |
||
| 15 | private $headElements = []; |
||
| 16 | |||
| 17 | public function __construct(WebRequest $request, WebApplication $app, Action $action, $actionId) { |
||

Our type inference engine has found an assignment to a property that is incompatible with the declared type of that property.
Either this assignment is in error or the assigned type should be added to the documentation/type hint for that property..
