屏蔽某个地区IP

BanIP.php

<?php

header("Content-type: text/html; charset=utf-8");
$verification = '安徽省';//需要屏蔽省份的IP
$ip = $_SERVER['REMOTE_ADDR'];//获取访客IP
$antecedents = $_SERVER['HTTP_REFERER'];//访客来路地址
$result = file_get_contents("http://ip.taobao.com/service/getIpInfo.php?ip=".$ip);
$address = json_decode($result,true);
//判断访客是否属于广东省，是否来自百度，是否来自谷歌
if($address['data']['region'] == $verification && strpos($antecedents, 'baidu') === false && strpos($antecedents, 'google') === false){
sleep(1800);//设置一个999999秒。看他们有没有这么好耐心。
Header("HTTP/1.1 204 No Content");
exit;

}
