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.\n";
 $this->res = rand(100, 999);
 sleep($nt);
 $this->lurl = $this->param;
 $this->param = '';
 } else {
 echo "线程[{$this->name}]等待任务..\n";
 }
 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[{$worker->res}].\n";
 break 2;
 }
 }
 sleep(1);
 }
}
echo "所有线程派发完毕,等待执行完成.\n";
//等待所有线程运行结束
while (count($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[{$threads->res}].\n";
 echo "[{$threads->name}]线程运行完成,退出.\n";
 //设置结束标志
 $threads->runing = false;
 unset($pool[$key]);
 }
 }
 echo "等待中...\n";
 sleep(1);
}
echo "所有线程执行完毕.\n";

希望本文所述对大家php程序设计有所帮助。
