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 |
||
| 12 | class ExistsAndDeletePermission |
||
| 13 | { |
||
| 14 | private $exists; |
||
| 15 | private $attached; |
||
| 16 | private $delete; |
||
| 17 | |||
| 18 | /** |
||
| 19 | * ExistsAndDeletePermission constructor. |
||
| 20 | * @throws \Illuminate\Contracts\Container\BindingResolutionException |
||
| 21 | */ |
||
| 22 | 3 | public function __construct() |
|
| 28 | |||
| 29 | /** |

||
| 31 | * @return bool |
