Proxy 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.
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
use Psr\Cache\CacheItemPoolInterface;
use Symfony\Component\Cache\Adapter\ProxyAdapter;
$psr6CachePool = \\ create your own cache pool instance that implements the PSR-6
\\ interface `CacheItemPoolInterface`
$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
);
