Question

我想在注册到我的网站时自动在PHP中找到用户的地理位置和IP地址。我该怎么做呢？

Answer 1

ip-api.com提供基于xml的免费api。

要使用api获取基于ip的位置，您可以使用：

$xml=simplexml_load_file("http://ip-api.com/xml/ipaddress");
echo $xml->RegionName;

Answer 2

使用codeigniter，您只需$ip = $this->input->ip_address()显示您的IP地址

Answer 3

您可以使用http://ipinfodb.com/ip_location_api.php

等第三方解决方案

您还可以使用以下代码：

<?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"];
?>

Just Try This code,this might help you. This a stand alon code you can create a simple file and copy this. But you have to create an google api key for this.  
 <?php
    if(isset($_POST['long'*emphasized text*]) && isset($_POST['lat'])){
        $key = 'YOUR-KEY_FROM-GOOGLE-API**strong text**';
        extract($_POST);
        $json = file_get_contents('https://maps.googleapis.com/maps/api/**strong text**geocode/json?latlng='.$lat.','.$long.'&key='.$key);
        $data = json_decode($json,true);
        foreach($data['results'][1]['address_components'] as $numbers){
            if( $numbers['types'][0] == 'administrative_area_level_2'){
                echo $numbers['long_name'];
            }
        }
    }else{
    ?>
    Location: <span id="location"></span>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-beta1/jquery.js"></script>
    <script>
    if (navigator.geolocation) {
      window.onload = function() {
      var startPos;
      var geoOptions = {
        maximumAge: 5 * 60 * 1000,
        timeout: 10 * 1000
      }

      var geoSuccess = function(position) {
        startPos = position;
        var data = {
            long: startPos.coords.longitude,
            lat: startPos.coords.latitude
        };
        var results = jQuery.ajax({
            type: 'POST',
            url: '#',
            data: data,
            async:false
            }).responseText;
        document.getElementById('location').innerHTML = results;
      };
      var geoError = function(position) {
        console.log('Error occurred. Error code: ' + error.code);
        // error.code can be:
        //   0: unknown error
        //   1: permission denied
        //   2: position unavailable (error response from location provider)
        //   3: timed out
      };

      navigator.geolocation.getCurrentPosition(geoSuccess, geoError, geoOptions);
    };

    }
    else {
      console.log('Geolocation is not supported for this Browser/OS version yet.');
    }
    </script>
    <?php
    }
    ?>

Answer 5

您可以通过以下方式获取IP值：

$theClientIp = $_SERVER['REMOTE_HOST'];

然后你可以像这样进行会话：

session_start();
$_SESSION['ip']=$theClientIp;

在任何地方你都可以通过回复这个

获得ip值

session_start(); $_SESSION[ip'];
