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 |
||
14 | View Code Duplication | final class UriFactoryDiscovery extends ClassDiscovery |
|
15 | { |
||
16 | /** |
||
17 | * Finds a URI Factory. |
||
18 | * |
||
19 | * @return UriFactory |
||
20 | * |
||
21 | * @throws NotFoundException |
||
22 | */ |
||
23 | 1 | public static function find() |
|
37 | } |
