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 namespace BuildR\ClassLoader\Modules\Transformable; |
||
20 | View Code Duplication | class TransformableModuleException extends Exception { |
|
|
|||
21 | |||
22 | const MESSAGE_NAME_OCCUPIED = "Transformer is already registered with name: %s"; |
||
23 | |||
24 | /** |
||
25 | * Used when try to register transformer with same name |
||
26 | * |
||
27 | * @param string $name The transformer name |
||
28 | * |
||
29 | * @return static |
||
30 | */ |
||
31 | public static function nameOccupied($name) { |
||
34 | |||
35 | /** |
||
36 | * @inheritDoc |
||
37 | */ |
||
38 | public function __construct($message = "", $code = 0, Exception $previous = NULL) { |
||
41 | |||
42 | } |

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.
