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 |
||
| 23 | final class Profiler extends ProfilerExtension |
||
| 24 | { |
||
| 25 | /** |
||
| 26 | * Enter $profile. |
||
| 27 | * |
||
| 28 | * @param \Twig\Profiler\Profile $profile Profile. |
||
| 29 | */ |
||
| 30 | View Code Duplication | public function enter(Profile $profile) |
|
| 37 | |||
| 38 | /** |
||
| 39 | * Leave $profile. |
||
| 40 | * |
||
| 41 | * @param \Twig\Profiler\Profile $profile Profile. |
||
| 42 | */ |
||
| 43 | View Code Duplication | public function leave(Profile $profile) |
|
| 50 | } |
