如何通过IP地址或精确位置获取用户的经度和纬度

Question

I want to get the geolocation (latitude and longitude) of a computer user by a php script. 我想通过php脚本获取计算机用户的地理位置（经度和纬度）。 I was using this one 我正在使用这个

<?php

// Get lat and long by address      
        $address = $dlocation; // Google HQ
        $prepAddr = str_replace(' ','+',$address);
        $geocode=file_get_contents('http://maps.google.com/maps/api/geocode/json?address='.$prepAddr.'&sensor=false');
        $output= json_decode($geocode);
        $latitude = $output->results[0]->geometry->location->lat;
        $longitude = $output->results[0]->geometry->location->lng;

?>

but the problem is that this uses real adresses and I just want the user to log in, ask him for the permission to track him (allow location) and if he accepts obtain the desired values (longitude and latitude). 但问题是，这使用真正的地址 ，我只是希望用户登录，询问他是否有权跟踪他（允许位置）以及他是否接受获得所需的值（经度和纬度）。 It could be by an IP adress or another way to pinpoint his location but the thing is I wanted this method to be pratically flawless regarding proxies and fakies. 这可能是由一个IP地址或另一种方式来找出他的位置，但事情是，我想这个方法是pratically无瑕关于代理和fakies。 Any idea on how I could do this? 有关如何做到这一点的任何想法？ Thank you very much! 非常感谢你！

I think this is what you want.simple and easy to use.Thanks to HTML5 see source here 我认为这就是你想要的。简单易用。感谢HTML5 在这里看到来源

<html>
<body>
<p id="demo">Click the button to get your coordinates:</p>
<button onclick="getLocation()">Try It</button>
<script>
var x=document.getElementById("demo");
function getLocation()
  {
  if (navigator.geolocation)
    {
    navigator.geolocation.getCurrentPosition(showPosition);
    }
  else{x.innerHTML="Geolocation is not supported by this browser.";}
  }
function showPosition(position)
  {
  x.innerHTML="Latitude: " + position.coords.latitude + 
  "<br>Longitude: " + position.coords.longitude;    
  }
</script>
