如何计算两个地址之间的距离 [英] How to calculate the distance between two addresses

问题描述

我想计算两个点之间的距离。该点的地址。

例如：

A点：肯尼迪国际机场，纽约，纽约州，美国的

点B：拉瓜地亚，纽约州，纽约州，美国的

现在我要计算的距离（通过道路）和A点和B点之间的旅行时间。

我怎样才能做到这一点？是否有可能使用谷歌地图API？你会如何​​解决这个问题？

解决方案

 ＆LT; PHP
从$ =SR格尔，海得拉巴
$到=库卡特帕尔莱，海得拉巴
从$ = urlen code（$来自）;
$为= urlen code（$到）;
$数据= file_get_contents(\"http://maps.googleapis.com/maps/api/distancematrix/json?origins=$from&destinations=$to&language=en-EN&sensor=false\");
$数据= json_de code（$的数据）;
$时间= 0;
$距离= 0;
的foreach（$数据 - ＆GT;行[0]  - ＆GT;元素$路）{
    $ +时间= $公路 - ＆GT; duration-＆GT;价值;
    $距离+ = $公路 - ＆GT;距离 - ＆GT;价值;
}
回声若要：数据 -  $＆GT; destination_addresses [0];
回声＆LT; BR /＆gt;中;
回声从：$数据 - ＆GT; origin_addresses [0];
回声＆LT; BR /＆gt;中;
回声时间：$时间秒。
回声＆LT; BR /＆gt;中;
回声距离：$距离米。
？＆GT;
 

注：上面你需要公里，时间H：M格式只是

更换

  $时间= $公路 - ＆GT; duration-＆gt;文字;
$距离= $公路 - ＆GT;距离 - ＆gt;文字;
 

I would like to calculate the distance between two points. The points are addresses.

Example:

Point A: JFK Airport, New York, NY, United States

Point B: La Guardia, New York, NY, United States

Now I want to calculate the distance (via roads) and the travel time between point A and point B.

How can I do that? Is it possible to use google maps API? How would you approach the problem?

解决方案

<?php 
$from = "sr nagar,hyderabad";
$to = "kukatpalle,hyderabad";
$from = urlencode($from);
$to = urlencode($to);
$data = file_get_contents("http://maps.googleapis.com/maps/api/distancematrix/json?origins=$from&destinations=$to&language=en-EN&sensor=false");
$data = json_decode($data);
$time = 0;
$distance = 0;
foreach($data->rows[0]->elements as $road) {
    $time += $road->duration->value;
    $distance += $road->distance->value;
}
echo "To: ".$data->destination_addresses[0];
echo "<br/>";
echo "From: ".$data->origin_addresses[0];
echo "<br/>";
echo "Time: ".$time." seconds";
echo "<br/>";
echo "Distance: ".$distance." meters";
?>

Note : above you need to km and time h:m format just replace with

$time      = $road->duration->text;
$distance  = $road->distance->text;
