extends abstract class Phalcon\Cache\Backend

implements Phalcon\Cache\BackendInterface

Allows to cache output fragments, PHP data and raw data using an XCache backend

));

  $cache = new Phalcon\Cache\Backend\Xcache($frontCache, array(
      'prefix' => 'app-data'

//Cache arbitrary data
$cache->save('my-data', array(1, 2, 3, 4, 5));
