如何计算两个地址之间的距离

Question

我想计算两点之间的距离.要点是地址.

例:

A点:肯尼迪机场,纽约,纽约,美国

B点:La Guardia,纽约,纽约,美国

现在我想计算距离(通过道路)和A点到B点之间的行程时间.

我怎样才能做到这一点？是否可以使用谷歌地图API？你会如何解决这个问题？

Answer 1

<?php 
$from = "sr nagar,hyderabad";
$to = "kukatpalle,hyderabad";
$from = urlencode($from);
$to = urlencode($to);
$apiKey= "";  
$data = file_get_contents("http://maps.googleapis.com/maps/api/distancematrix/json?origins=$from&destinations=$to&key=$apiKey&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";
?>

注意:上面你需要km和时间h:m格式只需替换

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