Implementsyii\base\Configurable, yii\base\ViewContextInterface
Available since version2.0
Source Code

Allows you to flush cache.

see list of available components to flush:

yii cache

flush particular components specified by their names:

yii cache/flush first second third

flush all cache components that can be found in the system

yii cache/flush-all

Note that the command uses cache components defined in your console application configuration file. If components configured are different from web application, web application cache won't be cleared. In order to fix it please duplicate web application cache components in console config. You can use any component names.

APC is not shared between PHP processes so flushing cache from command line has no effect on web. Flushing web cache could be either done by:

  • Putting a php file under web root and calling it via HTTP
  • Using Cachetool
