amphp/parallel
==============

[](#amphpparallel)

AMPHP is a collection of event-driven libraries for PHP designed with fibers and concurrency in mind. `amphp/parallel` provides *true parallel processing* for PHP using multiple processes or threads, *without blocking and no extensions required*.

To be as flexible as possible, this library comes with a collection of non-blocking concurrency tools that can be used independently as needed, as well as an "opinionated" worker API that allows you to assign units of work to a pool of worker processes.
