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 |
||
| 9 | View Code Duplication | class InvalidStatusException extends InvalidArgumentException |
|
| 10 | { |
||
| 11 | /** |
||
| 12 | * InvalidStatusException constructor. |
||
| 13 | * @param string $status the invalid status id that was supplied |
||
| 14 | * @param string $domain the name of the domain, model, or class that the status belongs to |
||
| 15 | * @param string $message custom message |
||
| 16 | * @param int $code |
||
| 17 | * @param Exception|null $previous |
||
| 18 | */ |
||
| 19 | public function __construct($status, $domain, $message = '', $code = 0, Exception $previous = null) |
||
| 33 | } |
