反向地址解析不起作用，Google Maps API v2

Question

I'm using google maps api v2 and I am sending coordinates to my program. The localisation on the map works fine but I never get the adress...

Here is my class:

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

        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])) {

                } else $cv=&$ary[$t];

I'm using getAdress in my programm to save the adress in the database, but it never seems to work properly even though the coordinates are correct...

Answer 1

Try this:

$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;

Answer 2

function getaddress($lat, $lng) {

    $url = 'http://maps.googleapis.com/maps/api/geocode/json?latlng=' . trim($lat) . ',' . trim($lng) . '&sensor=false';

    $json = @file_get_contents($url);
    $data = json_decode($json);
    $status = $data->status;
    if ($status == "OK")
        return $data->results[0]->formatted_address;
    else
        return false;
}
