public boolean delete (int | string $keyName) Deletes a value from the cache by its key

public array queryKeys ([string $prefix]) Query the existing cached keys

public boolean exists ([string $keyName], [long $lifetime]) Checks if cache exists and it isn’t expired

public _connect () Create internal connection to memcached

public flush () Immediately invalidates all existing items. Memcached does not support flush() per default. If you require flush() support, set $config[“statsKey”]. All modified keys are stored in “statsKey”. Note: statsKey has a negative performance impact. $cache = new \Phalcon\Cache\Backend\Libmemcached($frontCache, ["statsKey" => "_PHCM"]); $cache->save('my-data', array(1, 2, 3, 4, 5)); //'my-data' and all other used keys are deleted $cache->flush();

public boolean delete (int | string $keyName) Deletes a value from the cache by its key

public save ([int | string $keyName], [string $content], [long $lifetime], [boolean $stopBuffer]) Stores cached content into the file backend and stops the frontend

public get (mixed $keyName, [mixed $lifetime]) Returns a cached content

public long increment ([string $keyName], [mixed $value]) Increment of given $keyName by $value

public array queryKeys ([string | int $prefix]) Query the existing cached keys
