Proxy Cache Adapter
Edit this pageProxy Cache Adapter
This adapter wraps a PSR-6 compliant cache item pool interface. It is used to integrate
your application's cache item pool implementation with the Symfony Cache Component
by consuming any implementation of Psr\Cache\CacheItemPoolInterface.
It can also be used to prefix all keys automatically before storing items in the decorated pool, effectively allowing the creation of several namespaced pools out of a single one.
This adapter expects a Psr\Cache\CacheItemPoolInterface instance as its first parameter,
and optionally a namespace and default cache lifetime as its second and third parameters:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
use Psr\Cache\CacheItemPoolInterface;
use Symfony\Component\Cache\Adapter\ProxyAdapter;
// create your own cache pool instance that implements
// the PSR-6 CacheItemPoolInterface
$psr6CachePool = ...
$cache = new ProxyAdapter(
// a cache pool instance
CacheItemPoolInterface $psr6CachePool,
// a string prefixed to the keys of the items stored in this cache
$namespace = '',
// the default lifetime (in seconds) for cache items that do not define their
// own lifetime, with a value 0 causing items to be stored indefinitely (i.e.
// until the cache is cleared)
$defaultLifetime = 0
