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 |
||
8 | class MyDateInterval |
||
9 | { |
||
|
|||
10 | |||
11 | /** |
||
12 | * Returns date pattern for mysql (select part) |
||
13 | * @param int|string $dateInterval |
||
14 | * @return string |
||
15 | */ |
||
