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 |
||
| 7 | View Code Duplication | class StringSize extends Constraint |
|
| 8 | { |
||
| 9 | /** |
||
| 10 | * @var int |
||
| 11 | */ |
||
| 12 | protected $minSize; |
||
| 13 | |||
| 14 | /** |
||
| 15 | * @var int |
||
| 16 | */ |
||
| 17 | protected $maxSize; |
||
| 18 | |||
| 19 | public function __construct(int $minSize, int $maxSize = PHP_INT_MAX, string $errorMessage = null) |
||
| 28 | |||
| 29 | public function validate($content): bool |
||
| 43 | } |
