PHP+redis实现添加处理投票的方法，phpredis
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);
}
}
}
}
?>
