How to obtain latitude and longitude of a user by IP address or pinpoint location
提问by user111671
I want to get the geolocation (latitude and longitude) of a computer user by a php script. I was using this one
我想通过 php 脚本获取计算机用户的地理位置（纬度和经度）。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 adressesand 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). It could be by an IP adressor another way to pinpoint his location but the thing is I wanted this method to be praticallyflawless regarding proxies and fakies. Any idea on how I could do this? Thank you very much!
但问题是这使用了真实地址，我只希望用户登录，请求他允许跟踪他（允许位置），如果他接受，则获取所需的值（经度和纬度）。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。关于我如何做到这一点的任何想法？非常感谢！
