php 简单使用redis 队列示例

 public function redisAction(){
         $redis = new Redis();
         $redis->connect('127.0.0.1', 6379);
         echo "Connection to server sucessfully<br/>";
         //存储数据到列表中
         $redis->lpush("tutorial-list", "Redis");
         $redis->lpush("tutorial-list", "Mongodb");
         $redis->lpush("tutorial-list", "Mysql");
         // 获取存储的数据并输出
         $arList = $redis->lrange("tutorial-list", 0 ,5);
         echo "Stored string in redis------<br/>";
         echo"压入队列：<br/>";var_export($arList);
         echo "<br/>";
         // 获取列表长度
         $llen = $redis->llen('tutorial-list');
         while ($llen){
             echo "弹出数据：".$redis->lpop('tutorial-list')."<br/>";
             $llen = $redis->llen('tutorial-list');
         }
         // 获取存储的数据并输出
         $arList = $redis->lrange("tutorial-list", 0 ,5);
         echo "Stored string in redis------<br/>";
         var_export($arList);
     }
     //测试reds
     public function testredisAction(){

         $store=10;
         $redis=new Redis();
         $result=$redis->connect('127.0.0.1',6379);
         $res=$redis->llen('goods_store');
         echo $res."<br>";
         $count=$store-$res;
         for($i=0;$i<$count;$i++){
             $redis->lpush('goods_store',1);
         }
         echo $redis->llen('goods_store');    

     }
     public function buyAction(){
         //模拟下单操作
         //下单前判断redis队列库存量
         $redis=new Redis();
         $result=$redis->connect('127.0.0.1',6379);
         $count=$redis->lpop('goods_store');
         echo $count."<br>";
         echo $redis->llen('goods_store')."<br>";

         if(!$count){
             echo('error:no store redis');
         }else{

             //生成订单
             $order_sn=$this->build_order_no();
             echo $order_sn;
         }

     }
     //生成唯一订单号
     function build_order_no(){
         return date('ymd').substr(implode(NULL, array_map('ord', str_split(substr(uniqid(), 7, 13), 1))), 0, 8);
     }
