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。
