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 |
||
17 | View Code Duplication | class WPCOM_Additional_CSS_Manager { |
|
|
|||
18 | |||
19 | /** |
||
20 | * The site domain. |
||
21 | * |
||
22 | * @var string |
||
23 | */ |
||
24 | private $domain; |
||
25 | |||
26 | /** |
||
27 | * WPCOM_Additional_CSS_Manager constructor. |
||
28 | * |
||
29 | * @param string $domain the Site domain. |
||
30 | */ |
||
31 | public function __construct( $domain ) { |
||
34 | |||
35 | /** |
||
36 | * Register the Additional CSS nudge. |
||
37 | * |
||
38 | * @param \WP_Customize_Manager $wp_customize_manager The core customize manager. |
||
39 | */ |
||
40 | public function register_nudge( \WP_Customize_Manager $wp_customize_manager ) { |
||
49 | |||
50 | /** |
||
51 | * Get the nudge URL in WPCOM. |
||
52 | * |
||
53 | * @return string |
||
54 | */ |
||
55 | private function get_nudge_url() { |
||
58 | } |
||

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.
