Redis队列秒杀实现

<?php
//首先,加载一个Reids组件,
$redis = new Redis();
$resid->connect('127.0.0.1', 6379);
$reds_name = 'miaosha';
for ($i = 0;$i < 100;$i++) {
    $uid = rand(1000000, 9999999);
}
 
//接收用户的id,
//$uid = $_GET['uid'];
//获取redis里面已有的数量
$num = 10;
//如果当前人数少于10的时候,则加入这个队列
if ($redis->lLen($resid_name) < 10) {
    $redis->rPush($redis_name . $uid . '%' . microtime());
    echo $uid . '秒杀成功';        
}else{
    //如果当前人数已经达到10人,责任返回秒杀已完成
        echo '秒杀已结束';
}
$redis->close();
?>

<?php
inlcude_onceA './include/db.php';
$redis = new Redis();
$resid->connect('127.0.0.1', 6379);
$reds_name = 'miaosha';
$db = DB::getInstance();
//死循环
while(1) {
 //从队列最左侧取出一个值来
 $user = $redis->lPop($redis_name);
 //然后判断这个值是否存在
 if (!$user || $user == 'nil') {
   sleep(2);
   continue;
 }
//切割出时间, uid
$user_arr = explode('%', $user);
$insert_data = array(
    'uid' => $user_arr[0],
    'time_stamp' => $use_arr[1]]
);
  
 //保存到数据库中
 $res = $db->insert('redis_queue', $insert_data);:
 //数据库插入失败时回滚
  if (!$res) {
      $redis->rPop($redis_name, $user);
  }
 }
 //释放redis
 $redis->close();
  
  
}
