php redis thinkphp queue

This article mainly introduces the implementation code of thinkphp redis queue. The editor thinks it is quite good. Now I will share it with you and give it as a reference. Let’s follow the editor to take a look.

1. Install Redis and install the corresponding redis extension according to your PHP version (this step is briefly described)

1.1. Install php_igbinary.dll. php_redis.dll extension Here you need to pay attention to your php version as shown in the figure:

 

1.2, add extension=php_igbinary.dll; extension=php_redis.dll to the php.ini file Extension

ok The first step of redis environment construction has been completed. Take a look at phpinfo

The actual use of redis

2.1, the first step is to configure the redis parameters as follows. The default port for redis installation is 6379:

<?php
/* 数据库配置 */
return array(
 &#39;DATA_CACHE_PREFIX&#39; => &#39;Redis_&#39;,//缓存前缀
 &#39;DATA_CACHE_TYPE&#39;=>&#39;Redis&#39;,//默认动态缓存为Redis
 &#39;DATA_CACHE_TIMEOUT&#39; => false,
 &#39;REDIS_RW_SEPARATE&#39; => true, //Redis读写分离 true 开启
 &#39;REDIS_HOST&#39;=>&#39;127.0.0.1&#39;, //redis服务器ip,多台用逗号隔开;读写分离开启时,第一台负责写,其它[随机]负责读;
 &#39;REDIS_PORT&#39;=>&#39;6379&#39;,//端口号
 &#39;REDIS_TIMEOUT&#39;=>&#39;300&#39;,//超时时间
 &#39;REDIS_PERSISTENT&#39;=>false,//是否长连接 false=短连接
 &#39;REDIS_AUTH&#39;=>&#39;&#39;,//AUTH认证密码 
);
?>
Copy after login

2.2, redis is used in the actual function:

/**
  * redis连接
  * @access private
  * @return resource
  * @author bieanju
  */
 private function connectRedis(){
  $redis=new \Redis();
  $redis->connect(C("REDIS_HOST"),C("REDIS_PORT"));  
  return $redis;
 }
Copy after login

2.3, the core of the flash sale The problem is that in the case of large concurrency, the purchase will not exceed the inventory. This is the key to processing, so the idea is to do some basic data generation in the flash sale category in the first step:

//现在初始化里面定义后边要使用的redis参数
public function _initialize(){
  parent::_initialize();
  $goods_id = I("goods_id",&#39;0&#39;,&#39;intval&#39;);  
  if($goods_id){
   $this->goods_id = $goods_id;
   $this->user_queue_key = "goods_".$goods_id."_user";//当前商品队列的用户情况
   $this->goods_number_key = "goods".$goods_id;//当前商品的库存队列
  }
  $this->user_id = $this->user_id ? $this->user_id : $_SESSION[&#39;uid&#39;];  
 }
Copy after login

2.4, the second step This is the key point. Before entering the product details page, the user first queues the inventory of the current product and stores it in redis as follows:

 /**
 * 访问产品前先将当前产品库存队列
 * @access public
 * @author bieanju
 */
 public function _before_detail(){
  $where[&#39;goods_id&#39;] = $this->goods_id;
  $where[&#39;start_time&#39;] = array("lt",time());
  $where[&#39;end_time&#39;] = array("gt",time());
  $goods = M("goods")->where($where)->field(&#39;goods_num,start_time,end_time&#39;)->find();
  !$goods && $this->error("当前秒杀已结束!");
  if($goods[&#39;goods_num&#39;] > $goods[&#39;order_num&#39;]){
   $redis = $this->connectRedis();
   $getUserRedis = $redis->hGetAll("{$this->user_queue_key}");
   $gnRedis = $redis->llen("{$this->goods_number_key}");
   /* 如果没有会员进来队列库存 */
   if(!count($getUserRedis) && !$gnRedis){   
    for ($i = 0; $i < $goods[&#39;goods_num&#39;]; $i ++) {
     $redis->lpush("{$this->goods_number_key}", 1);
    }
   }
   $resetRedis = $redis->llen("{$this->goods_number_key}");
   if(!$resetRedis){
    $this->error("系统繁忙,请稍后抢购!");
   }
  }else{
   $this->error("当前产品已经秒杀完!");
  }
   
 }
Copy after login

The next thing to do is to use ajax to asynchronously process the user's click on the purchase button to meet the conditions. The data enters the purchase queue (if the current user is not in the queue of the current product user, it enters the queue and pops an inventory queue, if it is, it throws,):

/**
  * 抢购商品前处理当前会员是否进入队列
  * @access public
  * @author bieanju
  */
 public function goods_number_queue(){
  !$this->user_id && $this->ajaxReturn(array("status" => "-1","msg" => "请先登录"));
  $model = M("flash_sale");
  $where[&#39;goods_id&#39;] = $this->goods_id;
  $goods_info = $model->where($where)->find();
  !$goods_info && $this->error("对不起当前商品不存在或已下架!"); 
  /* redis 队列 */ 
  $redis = $this->connectRedis();
  /* 进入队列 */
  $goods_number_key = $redis->llen("{$this->goods_number_key}");
  if (!$redis->hGet("{$this->user_queue_key}", $this->user_id)) {
   $goods_number_key = $redis->lpop("{$this->goods_number_key}");
  }
   
  if($goods_number_key){
   // 判断用户是否已在队列
   if (!$redis->hGet("{$this->user_queue_key}", $this->user_id)) {
    // 插入抢购用户信息
    $userinfo = array(
     "user_id" => $this->user_id,
     "create_time" => time()
    );    
    $redis->hSet("{$this->user_queue_key}", $this->user_id, serialize($userinfo));
    $this->ajaxReturn(array("status" => "1"));
   }else{
    $modelCart = M("cart");
    $condition[&#39;user_id&#39;] = $this->user_id;
    $condition[&#39;goods_id&#39;] = $this->goods_id;
    $condition[&#39;prom_type&#39;] = 1;
  $cartlist = $modelCart->where($condition)->count();
    if($cartlist > 0){
     $this->ajaxReturn(array("status" => "2"));
    }else{
     
     $this->ajaxReturn(array("status" => "1"));
     
    }
     
   }
    
  }else{
   $this->ajaxReturn(array("status" => "-1","msg" => "系统繁忙,请重试!"));
  }
 }
Copy after login

Attach a debugging function to delete the specified Queue value:

 public function clearRedis(){
   set_time_limit(0);
   $redis = $this->connectRedis();
   //$Rd = $redis->del("{$this->user_queue_key}");
   $Rd = $redis->hDel("goods49",&#39;用户id&#39;&#39;);
   $a = $redis->hGet("goods_49_user", &#39;用户id&#39;);
   if(!$a){
    dump($a);
   }
   
   if($Rd == 0){
    exit("Redis队列已释放!");   
   }
  }
Copy after login

Redis plays a key role in data storage and management, and has become the core of modern applications through its multiple data structures and persistence mechanisms. 1) Redis supports data structures such as strings, lists, collections, ordered collections and hash tables, and is suitable for cache and complex business logic. 2) Through two persistence methods, RDB and AOF, Redis ensures reliable storage and rapid recovery of data.

The Compatibility of IIS and PHP: A Deep Dive The Compatibility of IIS and PHP: A Deep Dive Apr 22, 2025 am 12:01 AM

IIS and PHP are compatible and are implemented through FastCGI. 1.IIS forwards the .php file request to the FastCGI module through the configuration file. 2. The FastCGI module starts the PHP process to process requests to improve performance and stability. 3. In actual applications, you need to pay attention to configuration details, error debugging and performance optimization.

What happens if session_start() is called multiple times? What happens if session_start() is called multiple times? Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.
