Try this code using the hostip.infoservice:
使用hostip.info服务试试这个代码：
$country=file_get_contents('http://api.hostip.info/get_html.php?ip=');
echo $country;
// Reformat the data returned (Keep only country and country abbr.)
$only_country=explode (" ", $country);
echo "Country : ".$only_country[1]." ".substr($only_country[2],0,4);

as PHP relies on server, the real-time location cant be provided only static location can be provided it is better to avoid to rely on the JS for location rather than using php. But there is a need to post the js data to php so that it can be easily be accesible to program on server
由于PHP依赖服务器，无法提供实时位置，只能提供静态位置，最好避免依赖JS定位，而不是使用php。但是需要将js数据发布到php中，这样就可以很容易地在服务器上进行编程

An IP gives you an quite unreliable location, you could Ajax the location upon load with JS if it isn't critical to have the location at first. (Also, the user need's to give you it's permission to access it.)
IP 为您提供了一个非常不可靠的位置，如果一开始位置并不重要，您可以在加载时使用 JS Ajax 位置。（此外，用户需要授予您访问它的权限。）

$url = "http://api.ipstack.com/122.167.180.20?access_key=ACCESS_KEY&format=1";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
