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 | } |

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.
