Http://pecl.php.net/package/pthreads
Download the TGZ package, which provides a number of examples sample code, the simplest is to open multiple threads to capture network resources:


  
   url = $url;    }    public function run() {        // 线程处理一个耗时5秒的任务        for($i=0;$i<5;$i++) {            echo '线程: '.date('H:i:s')."\n";            sleep(1);        }        $response = file_get_contents($this->url);        if ($response) {            $this->data = array($response);        }        echo "线程: 任务完成\n";    }}$request = new Request('hello.html');// 运行线程:start()方法会触发run()运行if ($request->start()) {    // 主进程处理一个耗时10秒的任务,此时线程已经工作    for($i=0;$i<10;$i++) {        echo '进程: '.date('H:i:s')."\n";        sleep(1);    }    // 同步线程并输出线程返回的数据    $request->join();    echo '线程返回数据: '.$request->data[0];}/*如果顺序执行,合计时间将是15秒,借助线程,则只需10秒.生成文件: echo 'Hello' > hello.html运行计时: time php req.php 查看线程: ps -efL|head -n1 && ps -efL|grep php*/

It is important to note that you do not use the echo output in the thread, otherwise unpredictable errors and behavior, such as garbled (garbled), can occur. Especially in non-CLI environments, such as APACHE/PHP-FPM.

PHP don't talk about multithreading, haha

I would also like to know ......... .......
