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:

24 | * The $key parameter can be string or array. |
||
25 | * If $key is string, the attribute value will be overwritten by $value |

27 | * If $key is an array, it will overwrite all the data in the object. |
