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 | } |
