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。
