php多线程的创建及使用

本篇文章主要介绍php多线程的创建及使用，感兴趣的朋友参考下，希望对大家有所帮助。

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";
