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 |
||
| 9 | trait ConfigureTrait |
||
| 10 | { |
||
| 11 | /** @var [] $config store the configuration in this array. */ |
||

|
|||
| 12 | private $config = []; |
||
| 13 | |||
| 14 | |||
| 15 | |||
| 16 | /** |
||
| 17 | * Read configuration from file or array, if a file, first check in |
||
