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 AnomalyModulePreferencesUpdateUserRelatedConfig extends Migration |
||
|
|
|||
| 13 | { |
||
| 14 | |||
| 15 | /** |
||
| 16 | * Run the migrations. |
||
| 17 | * |
||
| 18 | * @return void |
||
| 19 | */ |
||
| 20 | View Code Duplication | public function up() |
|
| 32 | |||
| 33 | /** |
||
| 34 | * Reverse the migrations. |
||
| 35 | * |
||
| 36 | * @return void |
||
| 37 | */ |
||
| 38 | View Code Duplication | public function down() |
|
| 50 | } |
||
| 51 |
You can fix this by adding a namespace to your class:
When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.
