我该如何根据IP地址确定用户的当前位置(我猜是这样工作的)。
我该如何根据IP地址确定用户的当前位置(我猜是这样工作的)。
<?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"];
?>
已编辑
<?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'];

$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'];
?>
<?php
$query = @unserialize (file_get_contents('http://ip-api.com/php/'));
if ($query && $query['status'] == 'success') {
echo 'Hey user from ' . $query['country'] . ', ' . $query['city'] . '!';
}
foreach ($query as $data) {
echo $data . "<br>";
}
?>
使用这个源代码尝试此代码。* 它有效!
使用hostip.info服务尝试以下代码:
$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);
IP地址提供的位置信息相对不可靠。如果位置信息不是必要的,您可以在JavaScript加载时使用Ajax获取位置信息。(此外,用户需要允许您访问该位置信息。)
旧的freegeoip API现已过时,将于2018年7月1日停止使用。
新的API来自ipstack。您需要在ipstack中创建帐户。然后,您可以在API URL中使用访问密钥。
$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'.
