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 | final class StringBlockExampleFactory implements ExampleFactoryInterface |
||
| 13 | { |
||
| 14 | /** |
||
| 15 | * @var FactoryInterface |
||
| 16 | */ |
||
| 17 | private $factory; |
||
| 18 | |||
| 19 | /** |
||
| 20 | * @var \Faker\Generator |
||
| 21 | */ |
||
| 22 | private $faker; |
||
| 23 | |||
| 24 | /** |

| 25 | * @var OptionsResolver |
||

This check looks from parameters that have been defined for a function or method, but which are not used in the method body.
