Class Phalcon\Mvc\Model\MetaData\Xcache¶extends abstract class Phalcon\Mvc\Model\MetaData implements Phalcon\Mvc\Model\MetaDataInterface, Phalcon\Di\InjectionAwareInterface Stores model meta-data in the XCache cache. Data will erased if the web server is restarted By default meta-data is stored for 48 hours (172800 seconds) You can query the meta-data by printing xcache_get(‘$PMM$’) or xcache_get(‘$PMM$my-app-id’) <?php
$metaData = new Phalcon\Mvc\Model\Metadata\Xcache(
[
"prefix" => "my-app-id",
"lifetime" => 86400,

);
