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 |
||
| 3 | class Ajde_Component_Resource extends Ajde_Component |

||
| 11 | |||
| 12 | public function process() |
||
| 16 | |||
| 17 | public function requireResource( |
||
| 31 | |||
| 32 | View Code Duplication | public function requirePublicResource( |
|
| 41 | |||
| 42 | View Code Duplication | public function requireRemoteResource( |
|
| 51 | } |
