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 |
||
| 16 | class UsersBinding extends AbstractBinding |
||
| 17 | { |
||
| 18 | |||
| 19 | /** |
||
| 20 | * Construct a users binding from a database connector |
||
| 21 | * |
||
| 22 | * @param PDO $database |
||
| 23 | * @throws BindingException |
||
| 24 | */ |
||
| 25 | public function __construct(PDO $database) |
||
| 29 | |||
| 30 | View Code Duplication | public function lookupByScreenName($screen_name, $params = []) |
|
| 46 | |||
