我在php中运行这段代码:
$jsonData = file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address=306%20Evarts%20St%20NE%20Washington,%20DC%2020002&key=<hidden>');
$data = json_decode($jsonData, true);
var_dump($data);
显示以下结果(重新格式化为可读):
array(2) {
["results"] => array(1) {
[0] => array(5) {
["address_components"] => array(7) {
[0] => array(3) {
["long_name"] => string(3) "306"

如何在结果中回声各种值，例如地址组件的long_name ?
您可以使用嵌套的foreach来循环数组ref: http://php.net/manual/en/control-structures.foreach.php
foreach($data['results'] as $result){
foreach ($result['address_components'] as $value) {
echo $value['long_name'] . '<br>';
}
}
您可以访问如下所示的响应数据:
$jsonData = file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address=306%20Evarts%20St%20NE%20Washington,%20DC%2020002&key=API_KEY');
$data = json_decode($jsonData, true);
if($data['status'] == 'OK'){
$latitude = $data['results'][0]['geometry']['location']['lat'];
$longitude = $data['results'][0]['geometry']['location']['lng'];
$formatted_address = $data['results'][0]['formatted_address'];
}
