我想知道Lat / Lng的地名。为此我找到了Google API。我写的程序是
<?php
$url = 'http://maps.googleapis.com/maps/api/geocode/json?latlng=13.74349%2C100.489067&sensor=false';
$data = json_decode(file_get_contents($url));
echo '<pre>';
print_r($data);
?>
输出如下

我不知道如何抓住顶部的address_components。我尝试使用$data[0]->results[0]->address_components等等。但它不起作用。请检查一下......谢谢。
答案 0 :(得分：2)
以下适用于我：
$data->results[0]->address_components[0]->long_name
您可能还想启用json_decode的assoc - 参数，以便将对象转换为关联数组。
E.g。
$data = json_decode(file_get_contents($url), true);
$data["results"][0]["address_components"][0]["long_name"]
