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 |
||
| 20 | View Code Duplication | class InvalidMethod extends LogicException implements Exception { |
|
|
|
|||
| 21 | |||
| 22 | /** |
||
| 23 | * Create a new instance of this exception from an invalid method. |
||
| 24 | * |
||
| 25 | * @since %VERSION% |
||
| 26 | * |
||
| 27 | * @param string|object $class The class that doesn't have the method. |
||
| 28 | * @param string $method The method that is missing. |
||
| 29 | * |
||
| 30 | * @return static |
||
| 31 | */ |
||
| 32 | public static function from_method( $class, $method ) { |
||
| 40 | } |

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.
