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 |
||
| 17 | class Purchases { |
||
| 18 | |||
| 19 | const OPTION_CACHE = 'jetpack_purchases'; |
||
| 20 | |||
| 21 | /** |
||
| 22 | * Return the purchases a site has made. |
||
| 23 | * |
||
| 24 | * @return mixed|false |
||
| 25 | */ |
||
| 26 | public function get() { |
||
| 36 | |||
| 37 | /** |
||
| 38 | * Fetches the sites purchases from WP.com and caches them in an option. |
||
| 39 | * |
||
| 40 | * @return bool|mixed |
||
| 41 | */ |
||
| 42 | public function get_from_wpcom() { |
||
| 66 | |||
| 67 | } |
