Question

如何根据IP确定用户的当前位置（我猜它是这样的。）

Answer 1

<?php
$user_ip = getenv('REMOTE_ADDR');
$geo = unserialize(file_get_contents("http://www.geoplugin.net/php.gp?ip=$user_ip"));
$country = $geo["geoplugin_countryName"];
$city = $geo["geoplugin_city"];
?>

Answer 2

<强>被修改

将freegeoip.net更改为ipinfo.io

<?php    
function get_client_ip() {
        $ipaddress = '';
        if (isset($_SERVER['HTTP_CLIENT_IP']))
            $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
        else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
            $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
        else if(isset($_SERVER['HTTP_X_FORWARDED']))
            $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
        else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
            $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
        else if(isset($_SERVER['HTTP_FORWARDED']))
            $ipaddress = $_SERVER['HTTP_FORWARDED'];
        else if(isset($_SERVER['REMOTE_ADDR']))
            $ipaddress = $_SERVER['REMOTE_ADDR'];
        else
            $ipaddress = 'UNKNOWN';
        return $ipaddress;
    }
 $PublicIP = get_client_ip(); 
 $json  = file_get_contents("http://ipinfo.io/$PublicIP/geo");
 $json  =  json_decode($json ,true);
 $country =  $json['country'];
 $region= $json['region'];
 $city = $json['city'];

?>

使用hostip.info服务尝试此代码：

$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);

Answer 4

// check item[]= is repeated four times
if(substr_count($list, "item[]=") == '4') {

   // strip the string to only numbers, then will need to check each number if between 1-4
   $numbers = preg_replace("/[^0-9]/","",$list);

   // strip the string to only numbers and the character after it, will need to ensure it is & (except for the last number)
   preg_replace("/[^0-9]/","",$list + 1);

}

使用此来源尝试此代码。它有效！

Answer 5

MaxMind GeoIP是一项很好的服务。他们还提供免费的城市级查询服务。

Answer 6

您可能需要查看GeoIP Country Whois Locator处的PHPClasses。

Answer 7

由于PHP依赖于服务器，实时位置不能提供，只能提供静态位置，最好避免依赖JS来定位而不是使用php。但是需要将js数据发布到php，以便可以轻松访问服务器上的程序

Answer 8

IP为您提供了一个非常不可靠的位置，如果首先拥有该位置并不重要，您可以使用JS加载Ajax位置。（此外，用户需要授予您访问权限的权限。）

Answer 9

旧的freegeoip API现已弃用，将于2018年7月1日停止使用。

新API来自{{3}}。您必须在ipstack中创建帐户。然后您可以使用API网址中的访问密钥。

$url = "http://api.ipstack.com/122.167.180.20?access_key=ACCESS_KEY&format=1";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);
$response = json_decode($response);
$city  = $response->city; //You can get all the details like longitude,latitude from the $response .
