Class yii\caching\ArrayCache

Inheritanceyii\caching\ArrayCache » yii\caching\Cache » yii\base\Component » yii\base\BaseObject
Implementsyii\base\Configurable, yii\caching\CacheInterface
Available since version2.0
Source Code https://github.com/yiisoft/yii2/blob/master/framework/caching/ArrayCache.php

ArrayCache provides caching for the current request only by storing the values in an array.

See yii\caching\Cache for common cache operations that ArrayCache supports.

Unlike the yii\caching\Cache, ArrayCache allows the expire parameter of set(), add(), multiSet() and multiAdd() to be a floating point number, so you may specify the time in milliseconds (e.g. 0.1 will be 100 milliseconds).

For enhanced performance of ArrayCache, you can disable serialization of the stored data by setting $serializer to false.

For more details and usage information on Cache, see the guide article on caching.
