GPS坐标不在网上发布

Question

我想将Android手机的gs坐标发布到网站上。我使用WAMP创建了一个服务器。使用网站www.000webhost.com进行了网站托管 下面是PHP代码和java代码...我正在手机上获取我的位置，但协调不会在网站上发布..

PHP代码

<?php
echo 'Hello, world!';
$json = $_GET['jsonpost'];//get the post you sent...
$data = json_decode($json); //decode the json formatted string...
print_r($data);
$id = $data->id;
$devid = $data->devid;
$latitude = $data->latitude;
$longitude = $data->longitude;
$service = $data->service;
$con = mysql_connect("","","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
mysql_select_db("a5234826_ul", $con);
$devid = $_POST['devid']; 
$latitude = $_POST['latitude'];
$longitude = $_POST['longitude'];
echo "devid" +$devid;
echo "latitude" + $latitude;
echo "longitude" + $longitude; 
$sql = "INSERT INTO  `a5234826_ul`.`locations` (
`id` ,
`devid` ,
`latitude` ,
`longitude` ,
`service`
)
VALUES (
NULL ,  '$devid',  '$latitude',  '$longitude', '$service'  
)";
if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
mysql_close($con);
echo json_encode($variable);
?>
