PHP+Redis 消息队列 实现高并发下注册人数统计的实例

<?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";
  }
}
