bootstrap框架的IP查询

利用bootstrap框架二次开发了ip查询的页面..
ip查询是基于淘宝API的函数...
域名whois查询,我是接入站长之家的...
新手做站.难免代码复杂...
效果请点击ip查询
以下是代码
<?php header("content-Type: text/html; charset=utf-8");$weburl=$_SERVER['SERVER_NAME'];$weblink="http://".$weburl."/";if(count($_GET)>0){$urlip=array_keys($_GET);$urlip=str_replace("_",".",$urlip[0]);}?>
