我已经设法从谷歌地图获得邮政编码的经度和纬度,但我无法获得两者之间的距离。下面的 url 给了我一些 JSON:
https://maps.googleapis.com/maps/api/distancematrix/json?origins=51.6896118,-0.7846495&destinations=51.7651382,-3.7914676&units=imperial&sensor=false
但我无法使用 PHP 将其剥离:
<?php
$du = "https://maps.googleapis.com/maps/api/distancematrix/json?origins=51.6896118,-0.7846495&destinations=51.7651382,-3.7914676&units=imperial&sensor=false";
$djd = json_decode(utf8_encode($du),true);
print("-".$djd."-");
?>
有人知道这是为什么吗?

以下工作得很好:
<?php
$pc1 = 'SA92NH';
$pc2 = 'HP270SW';
$url1 = "https://maps.googleapis.com/maps/api/geocode/json?address=".$pc1."&sensor=false";
$url2 = "https://maps.googleapis.com/maps/api/geocode/json?address=".$pc2."&sensor=false";
$url1_data = file_get_contents($url1);
$url2_data = file_get_contents($url2);
$json1_data = json_decode(utf8_encode($url1_data),true);
$json2_data = json_decode(utf8_encode($url2_data),true);
$longlat1 = $json1_data['results'][0]['geometry']['location']['lat'].",".$json1_data['results'][0]['geometry']['location']['lng'];
$longlat2 = $json2_data['results'][0]['geometry']['location']['lat'].",".$json2_data['results'][0]['geometry']['location']['lng'];
print($longlat1."<br>\n");
print($longlat2."<br>\n");
?>
