本文实例讲述了PHP使用Pthread实现的多线程操作。分享给大家供大家参考，具体如下：

<?php class vote extends Thread {  public $res  = "";  public $url  = array();  public $name  = "";  public $runing = false;  public $lc   = false;  public function __construct($name) {    $this->res  = "暂无,第一次运行.";    $this->param  = 0;    $this->lurl  = 0;    $this->name  = $name;    $this->runing = true;    $this->lc   = false;  }  public function run() {    while ($this->runing) {      if ($this->param != 0) {        $nt     = rand(1, 10);        echo "线程[{$this->name}]收到任务参数::{$this->param},需要{$nt}秒处理数据.";        $this->res  = rand(100, 999);        sleep($nt);        $this->lurl = $this->param;        $this->param  = "";      } else {        echo "线程[{$this->name}]等待任务..";      }      sleep(1);    }  }}//这里创建线程池.$pool[] = new vote("a");$pool[] = new vote("b");$pool[] = new vote("c");//启动所有线程,使其处于工作状态foreach ($pool as $w) {  $w->start();}//派发任务给线程for ($i = 1; $i < 10; $i++) {  $worker_content = rand(10, 99);  while (true) {    foreach ($pool as $worker) {      //参数为空则说明线程空闲      if ($worker->param=="") {        $worker->param = $worker_content;        echo "[{$worker->name}]线程空闲,放入参数{$worker_content},上次参数[{$worker->lurl}]结果[{$worker->res}].";        break 2;      }    }    sleep(1);  }}echo "所有线程派发完毕,等待执行完成.";//等待所有线程运行结束while (count($pool)) {  //遍历检查线程组运行结束  foreach ($pool as $key => $threads) {    if ($worker->param=="") {      echo "[{$threads->name}]线程空闲,上次参数[{$threads->lurl}]结果[{$threads->res}].";      echo "[{$threads->name}]线程运行完成,退出.";      //设置结束标志      $threads->runing = false;      unset($pool[$key]);    }  }  echo "等待中...";  sleep(1);}echo "所有线程执行完毕.";

希望本文所述对大家php程序设计有所帮助。
