屏蔽指定地区IP访问

<?php

if($de_json['data']['country'] == "中国" && $de_json['data']['region'] != "香港" && $de_json['data']['region'] != "台湾" && substr($_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.
