Shared Memory Adapter (sharedMemory)#

Factory: Cache::sharedMemory(string $namespace = 'default', int $segmentSize = 16777216)

Requirements:

  • ext-sysvshm

Highlights:

  • values shared across PHP processes on the same host

  • namespace-specific segment key strategy

  • good for host-local IPC cache use cases

Notes:

  • data is not portable across hosts

  • capacity limited by shared memory segment size

Example#

use Infocyph\CacheLayer\Cache\Cache;

$cache = Cache::sharedMemory('worker-bus', 8 * 1024 * 1024);
$cache->set('heartbeat:worker-1', time(), 15);
