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 |
||
| 7 | class CreateEnrollmentsTable extends Migration |
||
|
|
|||
| 8 | { |
||
| 9 | /** |
||
| 10 | * Run the migrations. |
||
| 11 | * |
||
| 12 | * @return void |
||
| 13 | */ |
||
| 14 | View Code Duplication | public function up() |
|
| 42 | |||
| 43 | /** |
||
| 44 | * Reverse the migrations. |
||
| 45 | * |
||
| 46 | * @return void |
||
| 47 | */ |
||
| 48 | public function down() |
||
| 52 | } |
||
| 53 |
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.
