使用池和工人

Pooling 提供了 Worker 功能的更高级抽象，包括以 pthreads 所需方式管理引用。来自： http ： //php.net/manual/en/class.pool.php

池和工作人员提供更高级别的控制，并且易于创建多线程

<?php
// This is the *Work* which would be ran by the worker.
// The work which you'd want to do in your worker.
// This class needs to extend the \Threaded or \Collectable or \Thread class.

    private $workName;

    /**
     * @param string $workName
     * The work name wich would be given to every work.

        // The block of code in the constructor of your work,
        // would be executed when a work is submitted to your pool.

        $this->workName = $workName;
        printf("A new work was submitted with the name: %s\n", $workName);
    }

    public function run() {
        // This block of code in, the method, run
        // would be called by your worker.

// The ctor of \Pool accepts two parameters.
// First: The maximum number of workers your pool can create.
// Second: The name of worker class.

// the objects (works) which extends the \Threaded class.
