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 |
||
3 | class ExplanationPage extends Page |
||
|
|||
4 | { |
||
5 | |||
6 | public static $has_many = array( |
||
7 | 'Explanations' => 'Explanation' |
||
8 | ); |
||
9 | |||
10 | |||
11 | View Code Duplication | public function getCMSFields() |
|
22 | } |
||
23 | |||
52 |
You can fix this by adding a namespace to your class:
When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.
