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  | 
            ||
| 21 | View Code Duplication | class Sample3 extends \Risoluto\RisolutoControllerBase implements \Risoluto\RisolutoControllerInterface  | 
            |
| 22 | { | 
            ||
| 23 | // View関連の処理を使用する  | 
            ||
| 24 | use \Risoluto\RisolutoViewTrait;  | 
            ||
| 25 | |||
| 26 | /**  |
