PHP获取用户真实 IP , 淘宝IP接口获得ip地理位置

自己不需ip库,免更新。
淘宝IP库: http://ip.taobao.com

/**
 * 获取用户真实 IP
 */
function getIP()
{
    static $realip;
    if (isset($_SERVER)){
        if (isset($_SERVER["HTTP_X_FORWARDED_FOR"])){
            $realip = $_SERVER["HTTP_X_FORWARDED_FOR"];
        } else if (isset($_SERVER["HTTP_CLIENT_IP"])) {
            $realip = $_SERVER["HTTP_CLIENT_IP"];
        } else {
            $realip = $_SERVER["REMOTE_ADDR"];
        }
    } else {
        if (getenv("HTTP_X_FORWARDED_FOR")){
            $realip = getenv("HTTP_X_FORWARDED_FOR");
        } else if (getenv("HTTP_CLIENT_IP")) {
            $realip = getenv("HTTP_CLIENT_IP");
        } else {
            $realip = getenv("REMOTE_ADDR");
        }
    }
    return $realip;
}
/**
 * 获取 IP  地理位置
 * 淘宝IP接口
 * @Return: array
 */
function getCity($ip)
{
  $url="http://ip.taobao.com/service/getIpInfo.php?ip=".$ip;
  $ip=json_decode(file_get_contents($url));
  if((string)$ip->code=='1'){
    return false;
  }
  $data = (array)$ip->data;
  return $data;
}
