    The Threaded class

    (PECL pthreads >= 2.0.0)

    Вступ

    Threaded objects form the basis of pthreads ability to execute user code in parallel; they expose synchronization methods and various useful interfaces.

    Threaded objects, most importantly, provide implicit safety for the programmer; all operations on the object scope are safe.

    It's worth mentioning here that, since v2.0.0, 'Stackable' class was an alias for 'Threaded' class but has been removed since.

    However, this comes with a trade-off: Operations on the instance scope are slower than on plain PHP objects.

    Static properties are not affected as they are thread-local.
