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 |
||
| 6 | View Code Duplication | class CreateRolesTable extends Migration |
|
| 7 | { |
||
| 8 | /** |
||
| 9 | * Run the migrations. |
||
| 10 | * |
||
| 11 | * @return void |
||
| 12 | */ |
||
| 13 | public function up() |
||
| 24 | |||
| 25 | /** |
||
| 26 | * Reverse the migrations. |
||
| 27 | * |
||
| 28 | * @return void |
||
| 29 | */ |
||
| 30 | public function down() |
||
| 34 | } |
