reverse geocoding not working, Google Maps API v2 - php

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_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());
$cv=&$ary[$t][count($ary[$t])-1];
} else $cv=&$ary[$t];
if (isset($r['attributes'])) {
foreach ($r['attributes'] as $k=>$v) $cv['_a'][$k]=$v;
}

$ary=&$cv['_c'];
} elseif ($r['type']=='complete') {
if (isset($ary[$t])) { // same as open

$cv=&$ary[$t][count($ary[$t])-1];
} else $cv=&$ary[$t];
if (isset($r['attributes'])) {
foreach ($r['attributes'] as $k=>$v) $cv['_a'][$k]=$v;
}
$cv['_v']=(isset($r['value']) ? $r['value'] : '');
} elseif ($r['type']=='close') {
$ary=&$ary['_p'];
}
}
$this->del_p($mnary);
return $mnary;
}

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;
}
