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 | * Filter an email |
||
12 | * |
||
13 | * The return value is the email, as expected by the \TraderInteractive\Filterer class. |
||
14 | * |
||
15 | * @param mixed $value The value to filter. |
||
16 | * |
||
17 | * @return string The passed in $value. |
||
18 | * |
||
19 | * @throws Exception if the value did not pass validation. |
||
20 | */ |
||
21 | public static function filter($value) : string |
||
34 | } |

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.
