Named and unnamed synchronization objects
The 'sync' extension introduces synchronization objects into PHP. Named and unnamed Mutex, Semaphore, Event, Reader-Writer, and named Shared Memory objects provide OS-level synchronization mechanisms on both *NIX (POSIX shared memory and pthread shared memory synchronization required) and Windows platforms. This extension is a direct port of and compatible with the cross platform 'sync' library: https://github.com/cubiclesoft/cross-platform-cpp
