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

Array

    [0] => stdClass Object
        (
            [results] => Array

我不知道如何抓住address_components顶部。我尝试使用$data[0]->results[0]->address_components等。但它不起作用。请检查一次...谢谢。

以下对我有用:

$data->results[0]->address_components[0]->long_name

您可能还希望启用json_decodeassoc-parameter 以便将对象转换为关联数组。
例如

$data = json_decode(file_get_contents($url), true);
$data["results"][0]["address_components"][0]["long_name"]
