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 |
||
12 | class Cv extends AbstractRepository |
||
13 | { |
||
14 | /** |
||
15 | * Look for an drafted Document of a given user |
||
16 | * |
||
17 | * @param $user |
||
18 | * @return \Cv\Entity\Cv|null |
||
|
|||
19 | */ |
||
20 | View Code Duplication | public function findDraft($user) |
|
39 | } |
||

This check compares the return type specified in the
@return
annotation of a function or method doc comment with the types returned by the function and raises an issue if they mismatch.
