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 |
||
11 | View Code Duplication | class Stencil_Hierarchy_Category extends Stencil_Abstract_Hierarchy { |
|
12 | /** |
||
13 | * Stencil_Hierarchy_Category constructor. |
||
14 | */ |
||
15 | public function __construct() { |
||
32 | } |
