使用Google API获取两个位置之间的距离。的PHP

Question

I m trying to calculate distance between two location using API key and PHP as well. 我正在尝试使用API密钥和PHP计算两个位置之间的距离。 I tried two different codes that i found online. 我尝试了两个在网上找到的不同代码。 both of them have some sort of problem. 他们两个都有某种问题。

Two codes, the first one has an error message as "This API project is not authorized to use this API.", while the other code doesn't calculate the distance at all. 有两个代码，第一个有错误消息，例如“此API项目无权使用此API。”，而另一个代码根本不计算距离。

<?php

    // Google API key
    $apiKey = 'my key';

    // Change address format
    $formattedAddrFrom    = str_replace(' ', '+', $addressFrom);
    $formattedAddrTo     = str_replace(' ', '+', $addressTo);

    // Geocoding API request with start address
    $geocodeFrom = file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address='.$formattedAddrFrom.'&sensor=false&key='.$apiKey);
    $outputFrom = json_decode($geocodeFrom);
    if(!empty($outputFrom->error_message)){
        return $outputFrom->error_message;
    }

    // Geocoding API request with end address
    $geocodeTo = file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address='.$formattedAddrTo.'&sensor=false&key='.$apiKey);
    $outputTo = json_decode($geocodeTo);
    if(!empty($outputTo->error_message)){
        return $outputTo->error_message;

    // Get latitude and longitude from the geodata

    // Calculate distance between latitude and longitude
    $theta    = $longitudeFrom - $longitudeTo;
    $dist    = sin(deg2rad($latitudeFrom)) * sin(deg2rad($latitudeTo)) +  cos(deg2rad($latitudeFrom)) * cos(deg2rad($latitudeTo)) * cos(deg2rad($theta));
    $dist    = acos($dist);
    $dist    = rad2deg($dist);
    $miles    = $dist * 60 * 1.1515;

    // Convert unit and return distance
    $unit = strtoupper($unit);
    if($unit == "K"){
        return round($miles * 1.609344, 2).' km';

    }else{

$addressFrom = 'New Jersey, United States';
$addressTo   = 'New York, USA';

// Get distance in km
$distance = getDistance($addressFrom, $addressTo, "K");

Answer 1

Try this example function: 尝试以下示例函数：

function distance($lat1, $lon1, $lat2, $lon2, $unit) {
  $theta = $lon1 - $lon2;
  $dist = sin(deg2rad($lat1)) * sin(deg2rad($lat2)) +  cos(deg2rad($lat1)) * 
  cos(deg2rad($lat2)) * cos(deg2rad($theta));
  $dist = acos($dist);
  $dist = rad2deg($dist);
  $miles = $dist * 60 * 1.1515;
  $unit = strtoupper($unit);

  if ($unit == "K") {
    return ($miles * 1.609344);
  } else if ($unit == "N") {
    return ($miles * 0.8684);
  } else {
    return $miles;
  }
}

Units are K->Kilometers, M->Miles or N->Nautical Miles 单位为K->公里，M->英里或N->海里

You can follow the below link and this not require any google API 您可以点击以下链接，而无需任何Google API

https://gist.github.com/bmoren/22470de1cd47410e0902 https://gist.github.com/bmoren/22470de1cd47410e0902

and if you are trying to get distance by location than use Geo Coding API to get lat lng of particular address and than go through with this link 如果您要按位置获取距离，则可以使用Geo Coding API获取特定地址的纬度，然后通过此链接进行操作
