php获取当前ip<?php <br />
$user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];<br>
$user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];<br>
$URL='http://ip.taobao.com/service/getIpInfo.php?ip='.$user_IP;<br>
$fcontents = file_get_contents("$URL");<br>
$contents=json_decode($fcontents);<br>

另外在附一份tp自带的吧：
参考：https://github.com/liu21st/thinkphp/blob/master/ThinkPHP/Library/Org/Net/IpLocation.class.php/*<br>
* 根据ip地址获取所在城市<br>
*/<br>
protected function checkUserArea(){<br>
import("ORG.Net.IpLocation");<br>
$myip=get_client_ip();<br>
$Ip=new IpLocation("UTFWry.dat");//导入ip库 参考http://thinkphp.cn/extend/270.html 把下载的文件放在Lib\ORG\Net下<br>
$area=$Ip->getlocation($myip);<br>
return $area;<br>
}
