如何在php中从对象获取国家代码？

我是php/laravel的初学者

我有一个对象数组

这是示例对象：

Geocoder\Provider\Nominatim\Model\NominatimAddress Object
(
    [attribution:Geocoder\Provider\Nominatim\Model\NominatimAddress:private] => Data © OpenStreetMap contributors, ODbL 1.0. https://osm.org/copyright
    [category:Geocoder\Provider\Nominatim\Model\NominatimAddress:private] => boundary
    [displayName:Geocoder\Provider\Nominatim\Model\NominatimAddress:private] => Rumo, Comunità della Val di Non, TN, TAA, Italia
    [osmType:Geocoder\Provider\Nominatim\Model\NominatimAddress:private] => relation
    [osmId:Geocoder\Provider\Nominatim\Model\NominatimAddress:private] => 47201
    [type:Geocoder\Provider\Nominatim\Model\NominatimAddress:private] => administrative
    [coordinates:Geocoder\Model\Address:private] => Geocoder\Model\Coordinates Object
        (
            [latitude:Geocoder\Model\Coordinates:private] => 46.4610571
            [longitude:Geocoder\Model\Coordinates:private] => 10.9882457
        )

    [bounds:Geocoder\Model\Address:private] => Geocoder\Model\Bounds Object
        (
            [south:Geocoder\Model\Bounds:private] => 46.4218546
            [west:Geocoder\Model\Bounds:private] => 10.9308997
            [north:Geocoder\Model\Bounds:private] => 46.4840451
            [east:Geocoder\Model\Bounds:private] => 11.0481174
        )

    [streetNumber:Geocoder\Model\Address:private] => 
    [streetName:Geocoder\Model\Address:private] => 
    [subLocality:Geocoder\Model\Address:private] => 
    [locality:Geocoder\Model\Address:private] => Rumo
    [postalCode:Geocoder\Model\Address:private] => 
    [adminLevels:Geocoder\Model\Address:private] => Geocoder\Model\AdminLevelCollection Object
        (
            [adminLevels:Geocoder\Model\AdminLevelCollection:private] => Array
                (
                    [1] => Geocoder\Model\AdminLevel Object
                        (
                            [level:Geocoder\Model\AdminLevel:private] => 1
                            [name:Geocoder\Model\AdminLevel:private] => TAA
                            [code:Geocoder\Model\AdminLevel:private] => 
                        )

                    [2] => Geocoder\Model\AdminLevel Object
                        (
                            [level:Geocoder\Model\AdminLevel:private] => 2
                            [name:Geocoder\Model\AdminLevel:private] => Comunità della Val di Non
                            [code:Geocoder\Model\AdminLevel:private] => 
                        )

                )

        )

    [country:Geocoder\Model\Address:private] => Geocoder\Model\Country Object
        (
            [name:Geocoder\Model\Country:private] => Italia
            [code:Geocoder\Model\Country:private] => IT
        )

    [timezone:Geocoder\Model\Address:private] => 
    [providedBy:Geocoder\Model\Address:private] => nominatim
)

我的php代码：

foreach (app('geocoder')->geocode($request->input('city'))->get() as $key => $value) {
            //echo $value->country->code;
            echo"<pre>"; print_r($value); echo"</pre>";
        }

等

我该怎么做？

要使用

Geocoder

获取国家代码，请使用

StringFormatter

类

$formatter=new\Geocoder\formatter\StringFormatter（）；
$countryCode=$formatter->format（$location，'%c'）；

中列出了其他有用的格式

• 街道号码：%n
• 街道名称：%S
• 城市（地区）：%L
• 市区（次区域）：%D
• 邮政编码：%z
• 管理员级别名称：%A1、%A2、%A3、%A4、%A5
• 管理员级别代码：%a1、%a2、%a3、%a4、%a5
• 国家：%C
• 国家代码：%c
• 时区：%T

Sooo。。。。什么是

print\r

输出？因为它看起来像，如果。。。else条件，您基本上在那里？返回错误：传递给Geocoder\Formatter\StringFormatter:：format（）的参数1必须实现接口Geocoder\Location，给定的Illumb\Support\Collection实例，在934行的/var/www/appname/app/Http/Controllers/FrontendController.php中调用，您将哪个变量设置为

$location

？我有以下代码：$res=app（'geocoder'）->geocode（$request->input（'city'）->get（）$formatter=new\Geocoder\formatter\StringFormatter（）$countryCode=$formatter->format（$res，%c'）@GOSLSC给它一个单一的结果

foreach（…作为$value）{$formatter->format（$value，'%c'）；

It's correct
It's correct
