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 |
||
18 | View Code Duplication | class IsArray extends AbstractPropertyValidator implements PropertyValidatorInterface |
|
19 | { |
||
20 | const DIC_NAME = 'IsArrayValidator'; |
||
21 | const MESSAGE_TEMPLATE = '"%s" is not an array'; |
||
22 | |||
23 | /** |
||
24 | * @inheritDoc |
||
25 | */ |
||
26 | 3 | public function isValid($property, JobEntityInterface $jobEntity) |
|
34 | } |
