UPDATED

<?
$dbname            ='test'; //Name of the database
$dbuser            =''; //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());

    Html Page

    body onload="initMap()" //you forget to close it.
    
div id="map"

    Made below change in html file.

    script src="http://maps.google.com/maps/api/js?v=3&sensor=false"    type="text/javascript"
script type="text/javascript" src="js/jquery.js"
script type="text/javascript">
    var icon = new google.maps.MarkerImage("http://maps.google.com/mapfiles/ms/micons/blue.png",
    new google.maps.Size(32, 32), new google.maps.Point(0, 0),
    new google.maps.Point(16, 32));
    var center = null;
    var map = null;
    var currentPopup;
    var bounds = new google.maps.LatLngBounds();
    function addMarker(lat, lng, info)
    {
        var pt = new google.maps.LatLng(lat, lng);
        bounds.extend(pt);
        var marker = new google.maps.Marker(
        {
            position: pt,
            icon: icon,
            map: map
        });
        var popup = new google.maps.InfoWindow(
        {
            content: info,
            maxWidth: 300
        });

        google.maps.event.addListener(marker, "click", function()
    {
        if (currentPopup != null)
        {
            currentPopup.close();
            currentPopup = null;
        }
        popup.open(map, marker);
        currentPopup = popup;
    });
    google.maps.event.addListener(popup, "closeclick", function()
    {
        map.panTo(center);
        currentPopup = null;
    });
}

    function initMap()
    {
    map = new google.maps.Map(document.getElementById("map"), {
    center: new google.maps.LatLng(0, 0),
    zoom: 14,
    mapTypeId: google.maps.MapTypeId.ROADMAP,
    mapTypeControl: false,
    mapTypeControlOptions:
    {
    style: google.maps.MapTypeControlStyle.HORIZONTAL_BAR
    },
    navigationControl: true,
    navigationControlOptions:
    {
    style: google.maps.NavigationControlStyle.SMALL
    }
    });

    // getjson code goes here which is as below because i was unable to format it here so i wrote it downward.

center = bounds.getCenter();
map.fitBounds(bounds);

    }
    /script>


    $.getJSON('googlescript.php', function(items)
    {
    for (var i = 0; i < items.length; i++)
    {
    (function(item)
    {
    addMarker(item.lat, item.long, item.name + ' ' + item.desc);
    })(items[i]);
    }

    });

    I have used $.getJSON('googlescript.php', so you need to create a googlescript.php file and paste below code in it.

    $query = mysql_query("SELECT * FROM manu")or die(mysql_error());

header('Content-Type: application/json');

$rows = array();
while ($row = mysql_fetch_array($query))
{
    $rows[] = $row;
}
echo json_encode($rows);
exit;

    ?>

    Now check it in action and I’m sure you will get result that you wanted.
    Do not forget to change jquery path and change database connection setting and please place jquery path proper.
