YII使用beanstalk队列

转载于:http://blog.csdn.net/yao970953039/article/details/41821387

1.系统centos 我是直接使用yum install beanstalk安装的

2.下载beanstalk的php扩展包 放在extensions

//控制器往队列里面塞任务  @author yao
Yii::import('application.extensions.SendSmsBeanstalk');

class AController extends CController{

    public function actionIndex(){
        for($i=0;$i<1000;$i++){
            SendSmsBeanstalk::sendSms('sendsms_'.$i);
        }
    }

    public function actionA(){
        SendSmsBeanstalk::handleMessage();
    }
}

        while($job = $beanstalk->reserve(2)){//这里我写了单个任务只执行2秒。防止超时。本地测试的时候 没写超时会一直执行下去，哪怕队列里面已经没有任务
            //处理任务
            $result = $job['body'];

            if ($result) {<span style="font-family: Arial, Helvetica, sans-serif;">//这里可以写逻辑 todo</span>

            //删除任务
