$key mixed a key identifying the value to be cached. This can be a simple string or a complex data structure consisting of factors representing the key.
$value mixed the value to be cached
$duration integer default duration in seconds before the cache will expire. If not set, default [[ttl]] value is used.
$dependency yii\caching\Dependency dependency of the cached item. If the dependency changes, the corresponding value in the cache will be invalidated when it is fetched via [[get()]]. This parameter is ignored if [[serializer]] is false.
