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 | ||
| 19 | final class PluginClient implements HttpClient, HttpAsyncClient | ||
| 20 | { | ||
| 21 | /** | ||
| 22 | * @var \Http\Client\Common\PluginClient | ||
| 23 | */ | ||
| 24 | private $pluginClient; | ||
| 25 | |||
| 26 | /** | ||
| 27 | * @param HttpClient|HttpAsyncClient $client | ||
| 28 | * @param Plugin[] $plugins | ||
| 29 |      * @param array                      $options { | ||
| 30 | * | ||
| 31 | * @var int $max_restarts Number of times plugins may initiate a restart of the plugin chain. Defaults to 10. | ||
| 32 | * } | ||
| 33 | * | ||
| 34 | * @throws \RuntimeException if client is not an instance of HttpClient or HttpAsyncClient | ||
| 35 | */ | ||
| 36 | 8 | public function __construct($client, array $plugins = [], array $options = []) | |
| 40 | |||
| 41 | /** | ||
| 42 |      * {@inheritdoc} | ||
| 43 | */ | ||
| 44 | 4 | View Code Duplication | public function sendRequest(RequestInterface $request) | 
| 52 | |||
| 53 | /** | ||

If you suppress an error, we recommend checking for the error condition explicitly:
