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 |

2 | View Code Duplication | class Page404 extends Template { |
|
3 | public function __construct() { |
||
22 | } |
||
23 | ?> |
||
24 |
You can fix this by adding a namespace to your class:
When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.
