屏蔽指定地区IP访问

<?php

if ($HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"])
{
$ip = $HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"];
}
elseif ($HTTP_SERVER_VARS["HTTP_CLIENT_IP"])
{
$ip = $HTTP_SERVER_VARS["HTTP_CLIENT_IP"];
}
elseif ($HTTP_SERVER_VARS["REMOTE_ADDR"])
{
$ip = $HTTP_SERVER_VARS["REMOTE_ADDR"];
}
elseif (getenv("HTTP_X_FORWARDED_FOR"))
{
$ip = getenv("HTTP_X_FORWARDED_FOR");
}
elseif (getenv("HTTP_CLIENT_IP"))
{
$ip = getenv("HTTP_CLIENT_IP");
}
elseif (getenv("REMOTE_ADDR"))
{
$ip = getenv("REMOTE_ADDR");
}
else
{
$ip = "Unknown";
}  

$query = (file_get_contents('http://ip.taobao.com/service/getIpInfo.php?ip='. $ip ));
$de_json = json_decode($query, true);
if($de_json['data']['country'] == "中国" && $de_json['data']['region'] != "香港" && $de_json['data']['region'] != "*" && substr($_SERVER['REQUEST_URI'],1,4) !='link')
{
?>
  你的地区不可访问
<?php
  exit();
}

        //  PUBLIC_PATH
define('PUBLIC_PATH', __DIR__);

// Bootstrap
require PUBLIC_PATH.'/../bootstrap.php';

// Init slim routes
require BASE_PATH.'/config/routes.php';
    

替换到public的index.php即可.
