Can anyone help me?

<?php

$longitude = '-47.894317';
$latitude = '-15,7366566';
$timestamp = '1367349998375';

$mysql_id = mysql_connect('127.0.0.1', 'root', '') or die(mysql_error());
mysql_select_db('dbLocation', $mysql_id) or die(mysql_error());

# Insert a row of information into the table "example"

mysql_query("INSERT INTO tbLocation( longitude, latitude, timestamp ) VALUES ($longitude, $latitude, $timestamp)") or die(mysql_error());


if($query)
{
echo "Data Inserted!";
$resultArr[0]['result'] = ˝true˝;
}
else
{
echo mysql_error();
$resultArr[0]['result'] = ˝false˝;
}

mysql_close($mysql_id);

?>
