下载tgz包,里面提供有众多examples示例代码,最简单的就是开启多个线程采集网络资源:

<code><?php class Request extends Thread {
    public $url;
    public $data;
    public function __construct($url) {
        $this->url = $url;
    }
    public function run() {
        // 线程处理一个耗时5秒的任务
        for($i=0;$iurl);
        if ($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($i=0;$ijoin();
    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
*/
</code>

值得注意的是,不要在线程里使用echo输出内容,否则会出现不可预知的错误和行为,比如乱码(garbled).尤其是在非CLI环境下,比如Apache/PHP-FPM.

php就不要谈多线程了吧,哈哈

我也想知道.........................
