分开操作

/**
 * 调用淘宝地址库
 * */
function ip_taobao($ip){
    $urlTaobao = 'http://ip.taobao.com/service/getIpInfo.php?ip='.$ip;
    $json = file_get_contents($urlTaobao);
    $jsonDecode = json_decode($json);
    $data['country'] = $jsonDecode->data->country;
    $data['province'] = $jsonDecode->data->region;
    $data['city'] = $jsonDecode->data->city;
    $data['isp'] = $jsonDecode->data->isp;
    return $data;
}
/**
 * 调用新浪地址库
 * */
function ip_sina($ip){
    $data = '';
    $urlSina = 'http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip='.$ip;
    $json = file_get_contents($urlSina);
    $jsonDecode = json_decode($json);
    if($jsonDecode == '-2'){
        $data['error'] = '未分配或者内网IP';
    }else{
        $data['country'] = $jsonDecode->country;
        $data['province'] = $jsonDecode->province;
        $data['city'] = $jsonDecode->city;
        $data['isp'] = $jsonDecode->isp;
        $data['district'] = $jsonDecode->district;
    }
    return $data;
}

　调用 

/**
     * 返回ip所在位置
     * */
    public function ip_address($ip=''){
       if (empty($ip)) $ip = request()->ip();
        $info = Model('site')->info();
        if($info['ip_library'] ==1){
            $arr= ip_taobao($ip);
        }else{
            $arr= ip_sina($ip);
        }
        $address = implode(' ',$arr);
        return $address;
    }

新的用法

$ip = Request()->ip();
        $ip_info = ip_sina($ip);
        if($ip_info['country']!='未分配或者内网IP'){
            $address = implode(' ',$ip_info);
        }else{
            $address = '未分配或者内网IP';
        }
        print_r($address);
