如何从经度和纬度获取谷歌地址的PHP

Question

I am trying to get google address from longitude and latitude. I tried it but not working

<?php 
$sql_query  = "SELECT * FROM `user_History` where uid = '$id'";
$stmt = $dbh->query($sql_query);
$i = 1;
while($row = $stmt->fetch( PDO::FETCH_ASSOC))
{
extract($row);              
?>
<td><?php  echo getaddress($row['lat'],$row['lon']); ?></td>
<?php }  ?>

My function is:

 <?php
 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 "no";
 }
 }

?>

And my google map api key is here:

<script src="http://maps.googleapis.com/maps/api/js?key=mykey1776135765176371&callback=initMap" type="text/javascript"></script>

It is not working. Returns no

In your api you are missing api key. According to the google docs you must specified api key.

Example here:

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