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:

| 12 | class Static_Property extends PersistentListItem { |
||
| 13 | public $path; |
||
| 14 | public $line; |
||
| 15 | public $class_name; |
||
| 16 | public $prop_name; |
||
| 17 | |||
| 18 | public function __construct( $path, $line, $class_name, $prop_name ) { |
