<?
$dbname ='survey'; //Name of the database
$dbuser ='root'; //Username for the db
$dbpass =''; //Password for the db
$dbserver ='localhost'; //Name of the mysql server
$dbcnx = mysql_connect ("$dbserver", "$dbuser", "$dbpass");
mysql_select_db("$dbname") or die(mysql_error());
?>
<?
$query = mysql_query("SELECT * FROM appreciation");
while ($row = mysql_fetch_array($query)){
$name=$row['idAppreciation'];
$lat=$row['latitude'];
$lon=$row['longitude'];
$desc=$row['zone'];
echo "addMarker($lat, $lon,'<b>$name</b><br/>$desc');";
