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 | View Code Duplication | class Post_ID_Condition extends Condition { |
|
| 9 | |||
| 10 | /** |
||
| 11 | * Check if the condition is fulfilled |
||
| 12 | * |
||
| 13 | * @param array $environment |
||
| 14 | * @return bool |
||
| 15 | */ |
||
| 16 | public function is_fulfilled( $environment ) { |
||
| 24 | } |
