use*_*671 4 php google-maps google-chrome
我想通过php脚本获取计算机用户的地理位置(经度和纬度).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;
?>
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).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.有关如何做到这一点的任何想法？非常感谢你!
我认为这就是你想要的.简单易用.谢谢HTML5 在这里看到来源
