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); }}} }?><html><head><meta http-equiv="refresh" content="1;url=https://itunes.apple.com/cn/app/san-guo-zhi15-ba-wangno-da-lu/id694974270?mt=8"><title>统计</title></head><body> <img src="loading.gif">Loading...</body></html>其中php连接mysql类mysql.class.php如下:
