Question

当我运行以下代码时，各个线程似乎按顺序执行，一次执行。我期待他们并行运行。我的代码有问题，还是我应该开始关注我的环境？我在Windows机器上运行Apache，PHP 7。

<?php
class Searcher extends Worker
{
    public $data = [];

    public function addData($data)
    {
        $this->data[] = $data;
    }
}




class MyThread extends Threaded
{
    public function __construct($param)
    {
        $this->param = $param;
    } 


    public function run()
    {
        sleep(3);
        $this->worker->addData(
            $this->param." - TIME: ".microtime(true)
        );
    }
}




$worker   = new Searcher();
$params = ['thread1', 'thread2', 'thread3', 'thread4', 'thread5', 'thread6', 'thread7'];

foreach ($params as &$param) {
    $worker->stack(new MyThread($param));
}

$worker->start();
$worker->join();

foreach ($worker->data as $data) {
    echo $data."<br/>";
}


?>

上面代码的输出总是这样：

thread1 - TIME: 1512249412.3757 
thread2 - TIME: 1512249415.7776
thread3 - TIME: 1512249419.1792 
thread4 - TIME: 1512249422.5813
thread5 - TIME: 1512249425.9825 
thread6 - TIME: 1512249429.384
thread7 - TIME: 1512249432.7859

Answer 1

好的，我现在知道了。

Worker不会并行运行所有堆叠的线程，它们会在当时执行一次。

要同时运行所有作业，必须使用Pool。

PHP Pthreads - 线程没有并行运行
