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

[php] view plaincopy

//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();
}
}

[php] view plaincopy

Yii::import(‘application.extensions.beanstalk.*‘);
class SendSmsBeanstalk extends CComponent{
//建立发短信任务
public static function sendSms($body){
//实例化beanstalk
$beanstalk = new Socket_Beanstalk();
if (!$beanstalk->connect()) {
exit(current($beanstalk->errors()));
}
//选择使用的tube
$beanstalk->useTube(‘hube_send_smss‘);
//往tube中增加数据
$put = $beanstalk->put(
23, // 任务的优先级.
0, // 不等待直接放到ready队列中.
60, // 处理任务的时间.
$body // 任务内容
);
if (!$put) {
return false;
}
$beanstalk->disconnect();
}
//处理消息
public static function handleMessage(){
//实例化beanstalk
$beanstalk = new Socket_Beanstalk();
if (!$beanstalk->connect()) {
exit(current($beanstalk->errors()));
}
$beanstalk->useTube(‘hube_send_smss‘);
//设置要监听的tube
$beanstalk->watch(‘hube_send_smss‘);
//取消对默认tube的监听，可以省略
$beanstalk->ignore(‘default‘);
while($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‘];
echo $job[‘id‘];echo ‘<br>‘;//打印任务ID
if ($result) {<span style="font-family: Arial, Helvetica, sans-serif;">//这里可以写逻辑 todo</span>

[php] view plaincopy

//删除任务
$beanstalk->delete($job[‘id‘]);
} else {
//休眠任务
$beanstalk->bury($job[‘id‘],‘‘);
}
}
$beanstalk->disconnect();
}

下方提供我找到的队列PHP版本core，不能上传附件。代码在下面
