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 | View Code Duplication | abstract class AbstractStatus implements TokenizedQueryInterface |
|
|
|||
12 | { |
||
13 | /** @var string unique resource identifier, received from mobile login request */ |
||
14 | protected $token; |
||
15 | |||
16 | /** |
||
17 | * @param string $token unique resource identifier, received from mobile login request |
||
18 | * @return self |
||
19 | */ |
||
20 | 28 | public function __construct($token) |
|
24 | |||
25 | /** |
||
26 | * Get token |
||
27 | * @return string |
||
28 | */ |
||
29 | 4 | public function getToken() |
|
33 | |||
34 | /** |
||
35 | * Get fields |
||
36 | * @return array |
||
37 | */ |
||
38 | 4 | public function getFields() |
|
44 | |||
45 | /** |
||
46 | * Validation constraints for request data validation |
||
47 | * @return Assert\Collection |
||
48 | */ |
||
49 | 4 | public function getValidationConstraints() |
|
57 | |||
58 | /** |
||
59 | * HTTP method to use |
||
60 | * @return string |
||
61 | */ |
||
62 | 4 | public function getMethod() |
|
66 | } |

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.
You can also find more detailed suggestions in the “Code” section of your repository.
