* ZendDataCache provides Zend data caching in terms of an application component.
*
* To use this application component, the [Zend Data Cache PHP extension](http://www.zend.com/en/products/server/)
* must be loaded.
* Application configuration example:
* ```php
* return [
* 'components' => [
* 'cache' => [
* 'class' => yii\caching\Cache::class,
* 'handler' => [
* 'class' => yii\caching\ZendDataCache::class,
* ],
* // ...
* ];
* ```
* See [[\Psr\SimpleCache\CacheInterface]] for common cache operations that ZendDataCache supports.
* For more details and usage information on Cache, see the [guide article on caching](guide:caching-overview).
