我想通过地理编码从给定的纬度和经度中检索地址。以下是一个网站提供的示例链接:
http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true
在这个例子中,我只需要纽约市(New York)的城市名和美国(United States)的国家名。但问题是这些单词作为long_name出现了多次。
我的问题是如何在PHP中解析这个JSON/XML文件,以便仅获取城市名称和国家名称。
http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true

$url= file_get_contents('http://maps.googleapis.com/maps/api/geocode/xml?latlng=40.714224,-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;
