This time I will bring you PHP Redis to make messages QueueDetailed explanation of the steps to count the number of registered people in high concurrency, PHP Redis to make statistics of the number of registered people in high concurrency of message queueNotesWhat are they? Here are actual cases. Let’s take a look.

Preface

Now more and more websites are beginning to focus on statistics and user behavioranalysis, as websites often use Function, how to make statistical performance higher is something we need to consider. This article uses Redis to optimize the statistical function (taking registration statistics as an example).

Traditional statistical functions directly operate the database and insert data into the table. Doing so will consume a lot of database performance.

Idea:

Here we use the redis queue. When registering, we first add it to the queue, and then dequeue it during processing. And add the number of people to redis.

Code:

<?php
//register.php 
$redis = new Redis();
$redis->connect('127.0.0.1',6379);
$i=0;
while(true){
  $i++;
  //假定一直有人在注册
  $redis->rpush("register_success",$i);
}
<?php
//deal.php
$redis = new Redis();
$redis->connect('127.0.0.1',6379);
while (true) {
  //list类型出队操作
  $value = $redis->lpop('register_success');
  if($value){
    echo "deal value : ".$value;
    //自增 添加注册人数统计  如果key不存在 则会初始化为0
    $redis->incr('register_num');
  }else{
    echo "deal finish";
  }
}
