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 |
||
| 16 | class ConsoleTarget extends \yii\log\Target |
||
| 17 | { |
||
| 18 | public $exportInterval = 1; |
||
| 19 | |||
| 20 | public static $styles = [ |
||
| 21 | LogLevel::EMERGENCY => [Console::FG_RED], |
||
| 22 | LogLevel::ALERT => [Console::FG_RED], |
||
| 23 | LogLevel::CRITICAL => [Console::FG_RED], |
||
| 24 | LogLevel::ERROR => [Console::FG_RED], |
||
| 25 | LogLevel::WARNING => [Console::FG_YELLOW], |
||
| 26 | ]; |
||
| 27 | |||
| 28 | public function export() |
||
| 29 | { |
||
| 30 | foreach ($this->messages as $message) { |
||
| 31 | $this->out($message[0], $message[1]); |
||
| 32 | } |
||
| 33 | } |
||
| 34 | |||
| 35 | View Code Duplication | public function out($level, $message) |
|
|
|
|||
| 36 | { |
||
| 37 | /* XXX add minimum log severity to show |
||
| 38 | * if ($level > $this->getLevel()) { |
||
| 39 | return; |
||
| 40 | }*/ |
||
| 41 | $style = self::$styles[$level]; |
||
| 42 | if ($style) { |
||
| 43 | $message = Console::ansiFormat($message, $style); |
||

||
| 45 | return; |

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.
