/**
 * ApcCache provides APCu caching in terms of an application component.
 *
 * To use this application component, the [APCu PHP extension](http://www.php.net/apcu) must be loaded.
 * In order to enable APCu for CLI you should add "apc.enable_cli = 1" to your php.ini.
 *
 * Application configuration example:
 *
 * ```php
 * return [
 *     'components' => [
 *         'cache' => [
 *             'class' => yii\caching\Cache::class,
 *             'handler' => [
 *                 'class' => yii\caching\ApcCache::class,
 *             ],
 *         ],
 *         // ...
 *     ],
 *     // ...
 * ];
 * ```
 *
 * See [[\Psr\SimpleCache\CacheInterface]] for common cache operations that ApcCache supports.
 *
 * For more details and usage information on Cache, see the [guide article on caching](guide:caching-overview).
