用PHP对JSON数据进行反编码

我有以下PHP代码：

<?php
$json = file_get_contents('https://maps.googleapis.com/maps/api/distancematrix/json?origins=1707%20Sixes%20Rd%20,%20Prince%20Frederick%20,%20MD,%2020678&destinations=2000%20Medical%20Pkwy%20,%20Annapolis%20,%20MD,%2021401&mode=driving&units=imperial');

$details = json_decode($json, TRUE);
?>

我想从中提取“37.8英里”。有人能帮忙吗？

试试这个：

$array = json_decode($details, true);
$distance = $array['rows'][0]['elements'][0]['distance']['text'];

---

不完全一样

$array = json_decode($details, true);
$distance = $array['rows'][0]['elements'][0]['distance']['text'];
