PHP使用Pthread实现的多线程操作实例

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。
