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 |
||
| 8 | class SitemapController extends Controller |
||
| 9 | { |
||
| 10 | |||
| 11 | private $sitemapFilePath; |
||
| 12 | |||
| 13 | View Code Duplication | public function initialize() |
|
| 20 | |||
| 21 | public function indexAction() |
||
| 48 | |||
| 49 | } |
||
| 50 |
If you access a property on an interface, you most likely code against a concrete implementation of the interface.
