extends abstract class Phalcon\Cache\Backend
implements Phalcon\Cache\BackendInterface, Phalcon\Di\InjectionAwareInterface, Phalcon\Events\EventsAwareInterface
Allows to cache output fragments, PHP data or raw data to a yac backend This adapter uses the special yacd key “_PHCY” to store all the keys internally used by the adapter
<?php
// Cache data for 2 days

'prefix' => "myproduct_"

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