Clearing Symfony cache for another application

Question

I would like to clear my frontend application\'s cache from an action in my backend application.

How can I achieve this?

Answer 1

This works for me. It removes all cached files from the given directory:

$cache_dir = sfConfig::get('sf_cache_dir').'/'.$app.'/'.$env.'/';

$cache = new sfFileCache(array('cache_dir' => $cache_dir));
$cache->clean();
