Phalcon\Cache\Multiple constructor

public push (Phalcon\Cache\BackendInterface $backend)

Adds a backend

public mixed get (string | int $keyName, [int $lifetime])

Returns a cached content reading the internal backends

public start (string | int $keyName, [int $lifetime])

Starts every backend

public save ([string $keyName], [string $content], [int $lifetime], [boolean $stopBuffer])

Stores cached content into all backends and stops the frontend
