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 namespace App\Modules\Reporting\Repositories\V1; |
||
| 5 | class ReportRepository extends AbstractRepository |
||
| 6 | { |
||
| 7 | /** |
||
| 8 | * Return the model full namespace. |
||
| 9 | * |
||
| 10 | * @return string |
||
| 11 | */ |
||
| 12 | protected function getModel() |
||
| 17 | |||
| 18 | /** |
||
| 19 | * Render the given report db view. |
||
| 20 | * |
||
| 21 | * @param integer $id |
||
| 22 | * @param array $relations |
||
| 23 | * @param array $columns |
||
| 24 | * @return object |
||
| 25 | */ |
||
| 26 | public function find($id, $relations = [], $columns = array('*')) |
||
| 43 | |||
| 44 | /** |
||
| 45 | * Render the given report db view based on the given |
||
| 46 | * condition. |
||
| 47 | * |
||
| 48 | * @param array $conditions array of conditions |
||
| 49 | * @param array $relations |
||
| 50 | * @param array $colunmns |
||
| 51 | * @return object |
||
| 52 | */ |
||
| 53 | public function first($conditions, $relations = [], $columns = array('*')) |
||
| 70 | } |
||
| 71 |
This check looks for variable assignements that are either overwritten by other assignments or where the variable is not used subsequently.
Both the
$myVarassignment in line 1 and the$higherassignment in line 2 are dead. The first because$myVaris never used and the second because$higheris always overwritten for every possible time line.
