这篇文章主要介绍了PHP+redis实现添加处理投票的方法,结合实例较为详细的分析了PHP+redis数据库操作的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了PHP+redis实现添加处理投票的方法。分享给大家供大家参考,具体如下:
- <?php
- header("Content-Type:text/html;charset=utf-8");
- include 'lib/mysql.class.php';
- $mysql_obj = mysql::getConn();
- if(class_exists('Redis')){
- //redis
- $redis = new Redis();
- $redis->pconnect('127.0.0.1', 6379);
- if(isset($_SERVER['HTTP_REFERER'])){
- $url_md5 = md5($_SERVER['HTTP_REFERER']);
- }
- $adve_key = 'adve';
- $adve_key_exists = 'adve_exists';
- if(!$redis->exists($adve_key_exists)){
- $list = $mysql_obj->fetch_array("select * from admin_online_adve");
- if($list){
- foreach ($list as $key => $value) {
- $url_hash = md5($value['adve_url']);
- $adve_hash_key = $adve_key.":".$url_hash;
- $id = $value['id'];
- $redis->set($adve_hash_key,$id);
- $redis->set($adve_key_exists,true);
- }
- }
- }
- $adve_new_key = $adve_key.':'.$url_md5;
- if($redis->exists($adve_new_key)){
- $adve_plus = $adve_new_key.":plus" ;
- if(!$redis->exists($adve_plus)){
- $redis->set($adve_plus,1);
- }else{
- $redis->incr($adve_plus);
- $num = $redis->get($adve_plus);
- if($num >100){
- $id = $redis->get($adve_new_key);
- // insert to sql;
- $mysql_obj->query("update admin_online_adve set adve_num=adve_num+$num where id=$id");
- $redis->set($adve_plus,1);
- }
- }
- }
- }
- ?>
