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 |
||
15 | class LockedBehavior extends Behavior |
||
16 | { |
||
17 | public $lockedAttribute; |
||
18 | |||
19 | public $valueLock = true; |
||
20 | public $valueUnlock = false; |
||
21 | |||
22 | public function events() |
||
28 | |||
29 | public function getDefaultValue($event) |
||
38 | |||
39 | View Code Duplication | public function lock() |
|
49 | |||
50 | View Code Duplication | public function unlock() |
|
61 | } |
||
62 |
This check looks from parameters that have been defined for a function or method, but which are not used in the method body.
