使用谷歌地图API获取两点间的行驶距离

I'm trying to get driving distance between two points using Google Maps API. Now, I have code which get direct distance:

我想用谷歌地图API求两点间的行驶距离。现在，我有直接距离的代码:

This function get lat and lng:

此函数为lat和lng:

function get_coordinates($city, $street, $province)
{
    $address = urlencode($city.','.$street.','.$province);
    $url = "http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=Poland";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    $response = curl_exec($ch);
    curl_close($ch);
    $response_a = json_decode($response);
    $return = array('lat' => $response_a->results[0]->geometry->location->lat, 'long' => $long = $response_a->results[0]->geometry->location->lng);

    return $return;
}

This function calculate distance between two points based on lat & lng:

该函数基于lat和lng计算两点间的距离:

function getDistanceBetweenPoints($lat1, $lon1, $lat2, $lon2) {
    $theta = $lon1 - $lon2;
    $miles = (sin(deg2rad($lat1)) * sin(deg2rad($lat2))) + (cos(deg2rad($lat1)) * cos(deg2rad($lat2)) * cos(deg2rad($theta)));
    $miles = acos($miles);
    $miles = rad2deg($miles);
    $miles = $miles * 60 * 1.1515;
    $kilometers = $miles * 1.609344;
    return $kilometers;
}

This function print distance by kilometers:

该函数按公里打印距离:

function get_distance($lat1, $lat2, $long1, $long2)
{
    /* These are two points in New York City */
    $point1 = array('lat' => $lat1, 'long' => $long1);
    $point2 = array('lat' => $lat2, 'long' => $long2);

    $distance = getDistanceBetweenPoints($point1['lat'], $point1['long'], $point2['lat'], $point2['long']);
    return $distance;
}

Usage:

用法:

$coordinates1 = get_coordinates('Katowice', 'Korfantego', 'Katowicki');
$coordinates2 = get_coordinates('Tychy', 'Jana Pawła II', 'Tyski');

echo 'Distance: <b>'.round(get_distance($coordinates1['lat'], $coordinates2['lat'], $coordinates1['long'], $coordinates2['long']), 1).'</b> km';

But this code get direct distance. I need driving distance. How I can get driving distance using google maps API?

但是这个代码有直接的距离。我需要开车的距离。如何使用谷歌地图API获取行驶距离?

Thanks for your help!

谢谢你的帮助!

OK, I found solution using distance matrix: https://developers.google.com/maps/documentation/distancematrix/#DistanceMatrixRequests

我找到了使用距离矩阵的解决方案:https://developers.google.com/maps/documentation/distancematrix/#DistanceMatrixRequests

This function get lat & lng from city, adress, province:

此功能从省(市)adress，市(市)获得lat & lng:

function get_coordinates($city, $street, $province)
{
    $address = urlencode($city.','.$street.','.$province);
    $url = "http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=Poland";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    $response = curl_exec($ch);
    curl_close($ch);
    $response_a = json_decode($response);
    $status = $response_a->status;

    if ( $status == 'ZERO_RESULTS' )
    {
        return FALSE;
    }
    else
    {
        $return = array('lat' => $response_a->results[0]->geometry->location->lat, 'long' => $long = $response_a->results[0]->geometry->location->lng);
        return $return;
    }
}

This function calculate driving distance and travel time duration:

该函数计算行驶距离和行驶时间:

function GetDrivingDistance($lat1, $lat2, $long1, $long2)
{
    $url = "https://maps.googleapis.com/maps/api/distancematrix/json?origins=".$lat1.",".$long1."&destinations=".$lat2.",".$long2."&mode=driving&language=pl-PL";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    $response = curl_exec($ch);
    curl_close($ch);
    $response_a = json_decode($response, true);
    $dist = $response_a['rows'][0]['elements'][0]['distance']['text'];
    $time = $response_a['rows'][0]['elements'][0]['duration']['text'];

    return array('distance' => $dist, 'time' => $time);
}

Usage:

用法:

$coordinates1 = get_coordinates('Tychy', 'Jana Pawła II', 'Śląskie');
$coordinates2 = get_coordinates('Lędziny', 'Lędzińska', 'Śląskie');
if ( !$coordinates1 || !$coordinates2 )
{
    echo 'Bad address.';
}
else
{
    $dist = GetDrivingDistance($coordinates1['lat'], $coordinates2['lat'], $coordinates1['long'], $coordinates2['long']);
    echo 'Distance: <b>'.$dist['distance'].'</b><br>Travel time duration: <b>'.$dist['time'].'</b>';
}

Return:

返回:

Distance: 11,2 km Travel time duration: 15 min

距离:11、2公里行程时间:15分钟。

You can do this by using Google Distance Matrix API:

可以使用谷歌距离矩阵API实现:

// $details = "http://maps.googleapis.com/maps/api/distancematrix/json?origins=Seattle&destinations=San+Francisco&mode=driving&sensor=false";

    //you can also pass latitude/longitude values in origins


   $details = "http://maps.googleapis.com/maps/api/distancematrix/json?origins=41.43206,-81.38992&destinations=San+Francisco&mode=driving&sensor=false";


    $json = file_get_contents($details);

    $details = json_decode($json, TRUE);

    echo "<pre>"; print_r($details); echo "</pre>";

This is the method I got. In it, you can enter any manual distance from sessions or database.

这是我得到的方法。在其中，您可以从会话或数据库输入任何手动距离。

$origin = urlencode($_SESSION['source1']);
$destination = urlencode($_SESSION['dest1']);

$url = "https://maps.googleapis.com/maps/api/distancematrix/json?origins=$origin&destinations=$destination&key=Your api key;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);
$response_a = json_decode($response, true);
?>

Now the tough part was how to show distance. Well, with research, I got this answer:

现在最难的部分是如何显示距离。通过研究，我得到了答案

<div class="">
  <?php echo $response_a['rows'][0]['elements'][0]['distance']['text']; ?>

</div>

You can print this result anywhere. It's working for me.

您可以在任何地方打印此结果。这对我的工作。

Distance matrix API will do job then no need to calculate coordinates by using address and then Distance!!

距离矩阵API将做的工作，然后不需要计算坐标通过使用地址和距离!!

Here is the API
https://maps.googleapis.com/maps/api/distancematrix/json?origins=orginaddress&destinations=destinationaddress&key=YOUR_API_KEY

这是API https://maps.googleapis.com/maps/api/distancematrix/json?origin =orginaddress&destinations= destinationaddress&key_key

PHP Code :

PHP代码:

$ch = "https://maps.googleapis.com/maps/api/distancematrix/json?origins=orginaddress&destinations=destinationaddress&key=YOUR_API_KEY";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);
$response_a = json_decode($response, true);
//print_( $response_a );
