反向地理編碼無效，Google Maps API v2

Question

我正在使用google maps api v2，並且正在向我的程序發送座標。在地圖上的定位工作正常，但我從來沒有得到過ADRESS ...

這裏是我的類：

class reverseGeoCoding { 
    //put your code here 
    private $result; 
    private $latitude=null; 
    private $longitude=null; 
    private $adresse=null;

     xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0); 
     xml_parse_into_struct($parser, $string, $vals, $index); 
     xml_parser_free($parser); 

     $mnary=array(); 
     $ary=&$mnary; 
     foreach ($vals as $r) { 
      $t=$r['tag']; 
      if ($r['type']=='open') { 
       if (isset($ary[$t])) { 
        if (isset($ary[$t][0])) $ary[$t][]=array(); else $ary[$t]=array($ary[$t], array());

我使用getAdress我PROGRAMM保存在數據庫中ADRESS，但它似乎從來沒有正常工作，即使座標是正確的......

試試這個：

$result = json_decode(file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true')); 
echo $result->results[0]->formatted_address;
