如何解析谷歌地图地理编码结果

【问题标题】：how to parse a Google Maps geocoding result如何解析谷歌地图地理编码结果
【发布时间】：2011-08-12 22:57:08
【问题描述】：

我想使用地理编码从给定的纬度和经度中检索地理地址， 使用网站上的给定示例

http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true

在这个例子中，我只需要城市名称纽约和国家名称，即美国。但问题是出现不止一种 这些词作为long_name。

我的问题是如何在 php 中解析这个 json/xml 以获得城市名称和国家/地区。

$url= file_get_contents('http://maps.googleapis.com/maps/api/geocode/xml?latlng=40.714‌​224,-73.961452&sensor=true'); 
$xml = simplexml_load_string($url); 
$tracks = $xml->result; 
$temp; $city; $country; 
foreach($tracks as $key) 
{ 
    foreach($key->address_component as $val) 
    { 
        $temp= $val->long_name; 
        if($val->type=="locality") 
        { 
          $city=$temp; 
        }else if($val->type=="country") 
       { 
         $country=$temp; 
       }  
    }  
  } 
  echo $country."<br />"; echo $city;

    我有一个适用于 Google Geocode JSON 结果的简单解决方案。这是一个简单的 for 循环，它在字符串数组中返回该短版本和长版本。只需调用函数并在参数中提供“类型”。

    string[] street_number = GetJSONValueBasedOnType(record.geocode, "street_number");

        public string[] GetJSONValueBasedOnType(NewGoogleGeocode gc, string WhatYouWant)
{
    string[] returns = new string[2];
    returns[0] = string.Empty;
    returns[1] = string.Empty;
    bool isInIt;

    foreach (var v in gc.results[0].address_components)
    {
        isInIt = false;
        foreach (var t in v.types)
        {
            if (t == WhatYouWant)
            {
                isInIt = true;
            }
        }
        if (isInIt)
        {
            returns[0] = v.short_name;
            returns[1] = v.long_name;
        }
    }
    return returns;
}

      【解决方案2】：

      您可以检查 google 响应 (json) 中的 3 个变量以查找当前城市名称。因此，该名称有 3 种不同的解释：

      Country
     |
AdministrativeArea
     |
     |_AdministrativeAreaName (cityname)
     |
     |_Locality_LocalityName (cityname)
     | 
     |_SubAdministrativeArea
                 |
                 |_Locality_LocalityName (cityname)



if ($this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->Locality->LocalityName != NULL) {

  $code['cityname'] = $this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->Locality->LocalityName;

} elseif ($this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->SubAdministrativeArea->Locality->LocalityName != NULL) {

  $code['cityname'] = $this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->SubAdministrativeArea->Locality->LocalityName;

}

      如果您有更多的地标，则需要遍历所有数组。

      • 谢谢你的回复，我已经用我自己的简单逻辑来解决这个问题并在这里分享以寻求帮助$url= file_get_contents('http://maps.googleapis.com/maps/api/geocode/xml?latlng=40.714224,-73.961452&amp;sensor=true'); $xml = simplexml_load_string($url); $tracks = $xml-&gt;result; $temp; $city; $country; foreach($tracks as $key) { foreach($key-&gt;address_component as $val){ $temp= $val-&gt;long_name; if($val-&gt;type=="locality") { $city=$temp; }else if($val-&gt;type=="country") { $country=$temp; } }} echo $country."&lt;br /&gt;"; echo $city;
