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 | final class InsertAction extends AbstractAction |
|
| 18 | { |
||
| 19 | /** The output action socket. */ |
||
| 20 | const SOCKET_OUTPUT = 'out'; |
||
| 21 | |||
| 22 | /** The array variable socket. */ |

| 25 | /** The index variable socket. */ |

| 26 | const SOCKET_INDEX = 'index'; |
||
| 27 | |||
| 28 | /** The value variable socket. */ |
||
| 29 | const SOCKET_VALUE = 'value'; |
