以下是使用guzzle的更清晰的工作版本:

你可以使用curl而不是guzzle，这只是一个简单的get请求。

    function ip_info($ip = NULL, $purpose = "location", $deep_detect = TRUE) {
        $output = NULL;

            $ip = $_SERVER["REMOTE_ADDR"];
            if ($deep_detect) {
                if (filter_var(@$_SERVER['HTTP_X_FORWARDED_FOR'], FILTER_VALIDATE_IP))
                    $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
                if (filter_var(@$_SERVER['HTTP_CLIENT_IP'], FILTER_VALIDATE_IP))
                    $ip = $_SERVER['HTTP_CLIENT_IP'];
            }
        }
        $purpose    = str_replace(array("name", "\n", "\t", " ", "-", "_"), NULL, strtolower(trim($purpose)));
        $support    = array("country", "countrycode", "state", "region", "city", "location", "address");
        $continents = array(
            "AF" => "Africa",

            "AS" => "Asia",

        );
        if (filter_var($ip, FILTER_VALIDATE_IP) && in_array($purpose, $support, true)) {
            $client = New \GuzzleHttp\Client();
            $ipdat = json_decode($client->request('GET','http://www.geoplugin.net/json.gp',$params = [

我的服务ipdata。Co提供5种语言的国家名称!以及组织，货币，时区，呼叫代码，旗帜，移动运营商数据，代理数据和Tor出口节点状态数据从任何IPv4或IPv6地址。

这个答案使用了一个非常有限的“测试”API键，仅用于测试几个调用。注册您自己的免费API密钥，每天最多可获得1500个开发请求。

它还具有极强的可扩展性，全世界有10个地区，每个地区每秒可以处理>万个请求!

选项包括;英语(en)、德语(de)、日语(ja)、法语(fr)及简体中文(za-CH)

$ip = '74.125.230.195';
$details = json_decode(file_get_contents("https://api.ipdata.co/{$ip}?api-key=test"));
echo $details->country_name;
//United States
echo $details->city;
//Mountain View
$details = json_decode(file_get_contents("https://api.ipdata.co/{$ip}?api-key=test/zh-CN"));
echo $details->country_name;
//美国

我正在使用ipinfodb.com api，并得到你正在寻找的东西。

它是完全免费的，你只需要注册他们获得你的api密钥。你可以包括他们的php类从他们的网站下载，或者你可以使用url格式检索信息。

以下是我正在做的:

我在我的脚本中包含了他们的php类，并使用下面的代码:

$ipLite = new ip2location_lite;
$ipLite->setKey('your_api_key');
if(!$_COOKIE["visitorCity"]){ //I am using cookie to store information
  $visitorCity = $ipLite->getCity($_SERVER['REMOTE_ADDR']);
  if ($visitorCity['statusCode'] == 'OK') {
    $data = base64_encode(serialize($visitorCity));
    setcookie("visitorCity", $data, time()+3600*24*7); //set cookie for 1 week
  }
}
$visitorCity = unserialize(base64_decode($_COOKIE["visitorCity"]));
echo $visitorCity['countryName'].' Region'.$visitorCity['regionName'];

这是它。

你可以使用http://ipinfo.io/获取ip地址的详细信息。

<?php
    function ip_details($ip)
    {
    $json = file_get_contents("http://ipinfo.io/{$ip}");
    $details = json_decode($json);
    return $details;
    }

    $details = ip_details(YoUR IP ADDRESS); 

    echo $details->city;
    echo "<br>".$details->country; 
    echo "<br>".$details->org; 
    echo "<br>".$details->hostname; /

    ?>

使用以下服务

1) http://api.hostip.info/get_html.php?ip=12.215.42.19

2)

$json = file_get_contents('http://freegeoip.appspot.com/json/66.102.13.106');
$expression = json_decode($json);
print_r($expression);

3) http://ipinfodb.com/ip_location_api.php

您可以使用http://www.geoplugin.net/上的简单API

$xml = simplexml_load_file("http://www.geoplugin.net/xml.gp?ip=".getRealIpAddr());
echo $xml->geoplugin_countryName ;


echo "<pre>";
foreach ($xml as $key => $value)
{
    echo $key , "= " , $value ,  " \n" ;
}
echo "</pre>";

函数使用

function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}

输出

United States
geoplugin_city= San Antonio
geoplugin_region= TX
geoplugin_areaCode= 210
geoplugin_dmaCode= 641
geoplugin_countryCode= US
geoplugin_countryName= United States
geoplugin_continentCode= NA
geoplugin_latitude= 29.488899230957
geoplugin_longitude= -98.398696899414
geoplugin_regionCode= TX
geoplugin_regionName= Texas
geoplugin_currencyCode= USD
geoplugin_currencySymbol= $
geoplugin_currencyConverter= 1

它让你有很多选择可以选择

谢谢
