我想从他们的邮政/邮政编码（加拿大/美国）的谷歌地理编码中获取用户城市、州/省、国家/地区。我以 JSON 格式检索数据：https ://developers.google.com/maps/documentation/geocoding/#JSON

问题是“address_components”的数量/顺序并不总是相同。我使用的是这样的：$geocodedinfo['results'][0]['address_components'][3]['short_name']; 但我很快意识到这并不总是省/州，因为有时谷歌会在'address_components'下添加一个额外的元素。

有没有办法仅针对我需要的细节（即：城市、州/省、国家/地区）解析结果？

编辑当我得到它时，我实际上解码了 JSONjson_decode($result, true)

您将不得不遍历结果。
大多数相关的 PHP 函数不支持多维数组，而那些支持的函数无论如何都会循环。

你可能会想要这样的东西：

foreach ($geocodedinfo["results"] as $result) {
    foreach ($result["address_components"] as $address) {
        // Repeat the following for each desired type
        if (in_array("country", $address["types"])) {
            $country = $address["long_name"];
        }
    }
}

试试看这个，http ://php.net/manual/en/control-structures.foreach.php它用于循环数组，你可以做类似的事情，

foreach ($result['results'][0]['address_components'] as $key => $val) 
    { 
    if (in_array('country', $result['results'][0]['address_components'][$key]['types'][0])) 
    { 
    echo $result['results'][0]['address_components'][$key]['long_name']; 
    } 
}

像这样的东西应该工作

您可以通过foreach循环运行结果并获取您正在寻找的数据。

我正在对 Google 类型的含义做出最好的猜测，我可能会不以为然。

$translate = array(
    'locality' => 'city',
    'administrative_area_level_3' => 'area', // not sure what this one is
    'administrative_area_level_2' => 'county', // regional district ?
    'administrative_area_level_1' => 'state', // province
    'country' => 'country',
    'postal_code' => 'zip', // postal code
);

$address_components = array( );
foreach ($geocodedinfo['results'][0]['address_components'] as $component) {
    $address_components[$translate[$component['type'][0]]] = $component['long_name'];
}

var_dump($address_components);

// 解析json响应 $jsondata = json_decode($data,true); $results = $jsondata['results'][0]; $addr =$results['formatted_address'];
