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 |
||
| 8 | class DeviceDetector extends BrowserDetector |
||
| 9 | { |
||
| 10 | public function detect(string $ua) |
||
| 16 | |||
| 17 | |||
| 18 | View Code Duplication | private function initResultObject() |
|
| 27 | |||
| 28 | View Code Duplication | private function setupResultObject() |
|
| 40 | } |
Overwriting private methods is generally fine as long as you also use private visibility. It might still be preferable for understandability to use a different method name.
