如何从反向地理编码JSON结果中获取格式化地址？

标签： php json google-maps geocoding reverse-geocoding

这是JSON输出：我想只获取formatted_address值＆amp; long_name＆amp;简称。我提到了人们已经问过的问题，但我说得不对。 提到：

get city from geocoder results?

               "lng" : 101.7874058
            },

MY PHP函数用于获取lat和lon的反向地理编码

public function get_location()
    {
        $this->location = $param;
         $location = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?latlng=2.993518,101.7874058&sensor=true');

         return $location;
    }

我尝试解析如下：

$search = new search();
$data = $search->get_location();//caries the JSON data
$return['json']= json_encode($data);
$data = json_decode($return['json'], true);

但是如何定位long_name，格式化地址等等？

以下示例演示了如何解析和访问Geocoding Service结果long_name＆amp; PHP中的short_name属性：

$json = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?latlng=2.993518,101.7874058&sensor=true');
$data = json_decode($json, true);


foreach ($data['results'] as $item) {
    if( !empty( $item['address_components'] ) ){
        $longName = $item['address_components'][0]['long_name']; 
        $shortName = $item['address_components'][0]['short_name']; 

        print_r('Long Name:' . $longName);
        print_r(' Short Name:' . $shortName);
    }

}

答案 1 :(得分：2)

首先，您可以在此处阅读有关地理编码器结果类型的所有信息 - ＆gt;的 https://developers.google.com/maps/documentation/geocoding/intro

为方便起见，我会将JSON转换为stdClass：

$location = json_decode($location);

然后解析它：

$geoResults = [];
foreach($location->results as $result){
    $geoResult = [];    
    foreach ($result->address_components as $address) {
        if ($address->types[0] == 'country') {
            $geoResult['country'] = $address->long_name;
        }
        if ($address->types[0] == 'administrative_area_level_1') {
            $geoResult['state'] = $address->long_name;
        }
        if ($address->types[0] == 'administrative_area_level_2') {
            $geoResult['county'] = $address->long_name;
        }
        if ($address->types[0] == 'locality') {
            $geoResult['city'] = $address->long_name;
        }
        if ($address->types[0] == 'postal_code') {
            $geoResult['postal_code'] = $address->long_name;
        }       
        if ($address->types[0] == 'route') {
            $geoResult['route'] = $address->long_name;
        }       
    }
    $geoResults[] = $geoResult;
}

现在你有一个带有命名属性的$geoResults数组：

Array
(
    [0] => Array
        (
            [route] => Jalan Sungai Chua
            [city] => Kajang
            [state] => Selangor
            [country] => Malaysia
            [postal_code] => 43000
        )

    [1] => Array
        (
            [city] => Kajang
            [state] => Selangor
            [country] => Malaysia
            [postal_code] => 43000
        )

    [2] => Array
        (
            [city] => Kajang
            [state] => Selangor
            [country] => Malaysia
            [postal_code] => 43000
        )

    [3] => Array
        (
            [city] => Kajang
            [state] => Selangor
            [country] => Malaysia
        )

    [4] => Array
        (
            [state] => Selangor
            [country] => Malaysia
        )

    [5] => Array
        (
            [postal_code] => 43000
            [state] => Selangor
            [country] => Malaysia
        )

    [6] => Array
        (
            [state] => Selangor
            [country] => Malaysia
        )

    [7] => Array
        (
            [state] => Selangor
            [country] => Malaysia
        )

    [8] => Array
        (
            [country] => Malaysia
        )

)

您可以迭代所有找到的城市，如下所示：

foreach($geoResults as $result) {
    echo isset($result['city']) ? $result['city'] : 'N/A';
    echo '<br>';
}
