The SyncSharedMemory class
(PECL sync >= 1.1.0)
A cross-platform, native, consistent implementation of named shared memory objects.
Shared memory lets two separate processes communicate without the need for complex pipes or sockets. There are several integer-based shared memory implementations for PHP. Named shared memory is an alternative.
Synchronization objects (e.g. SyncMutex) are still required to protect most uses of shared memory.
