I'am trying to create GIS web using google maps api v3, JSON, and postgresql. i can show multiple marker in mymap, but when I click on a marker and try to open the Info window only the last marker will response correctly.

The problem is if i try and assign content to the infowindow within a loop. Then when i click the marker, it only knows about the content from the very last iteration of the loop. i know the problem but don't know how to solve it. sorry for my bad english. any suggestion? here the code (json.php and index.php):

<?php
    $sql = "SELECT distinct org_id, customer_name, attribute16, attribute17 FROM gis where org_id = 41 OR org_id = 124";
    $data = pg_query($sql);
    $json = '{"enseval": {';
    $json .= '"customer":[ ';
    while($x = pg_fetch_array($data)){
        $json .= '{';
        $json .= '"id_customer":"'.$x['org_id'].'",
            "nama_customer":"'.htmlspecialchars($x['customer_name']).'",
            "x":"'.$x['attribute17'].'",
            "y":"'.$x['attribute16'].'"
        },';
    }
    $json = substr($json,0,strlen($json)-1);
    $json .= ']';
    $json .= '}}';

    echo $json;
?>
