Question

我在php中运行此代码：

$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);

具有以下结果（重新格式化为可读）：

array(2) {
    ["results"] => array(1) {
        [0] => array(5) {
            ["address_components"] => array(7) {

如何回显结果中的各种值，例如long_name地址组件？

Answer 1

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>';
    }
}

Answer 2

您可以访问响应数据，如下所示：

$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']; 
}

使用数组响应解析JSON URL
