谁能帮我处理这段代码...基本上我想从我的 MSSQL 数据库中输出带有标记位置的谷歌地图。我正在连接到数据库并从数据库中输出数据，没有任何问题。我的数据库中需要用到的值是纬度和经度

我只需要一些帮助将经纬度信息从数据库中获取到一个数组中，该数组可以传递给“var markers = createMarker”。任何人都可以提出任何代码或建议吗？

我尝试使用以下方法创建新标记，但没有成功。任何人都可以指出下面的代码有什么问题或给我任何建议吗？

  //<![CDATA[
    function load() {
      if (GBrowserIsCompatible()) {
        var map = new GMap2(
        document.getElementById("map"));
        map.addControl(new GSmallMapControl());
        map.addControl(new GMapTypeControl());
        map.addMapType(G_SATELLITE_3D_MAP);
        map.setCenter(
        new GLatLng(37.4419, -122.1419), 13);
        function createMarker(point, text, title) {
          var marker =
          new GMarker(point,{title:title});
          return marker;
        }
        <?php
        /*data base connection */


        /* Connect using Windows Authentication */       
        $conn = sqlsrv_connect($serverName, $connectionOptions);

        /* Check whether connnection is established */
        if($conn === false)
        {
            die(print_r(sqlsrv_errors(), true));
        }

        /* SQL query */
        $tsql = ("SELECT TOP 10 gps_lat
                ,gps_long
                FROM location");

        $result = sqlsrv_query($conn,$tsql);

        if( $result === false)
        {
            echo "Error in query preparation/execution.\n";
            die( print_r( sqlsrv_errors(), true));
        }

/*
BELOW IS THE ADJUSTED WHILE LOOP
*/
while($row = sqlsrv_fetch_array( $result )) {
    $lat = $row['gps_lat'];
    $long = $row['gps_long'];

        ?>      
        var marker = createMarker(  
        new GLatLng(<?php echo $Lat.','.$Long;?>)
        );
        map.addOverlay(marker);
        <?php } ?>
      }
    }
    //]]>
    </script>

我认为这会相当简单，但我似乎无法理解它。如果有不清楚的信息...

实际上，我确实设法通过通宵工作最终解决了这个问题，尝试了很多不同的事情......检索值的代码如下。

    $lat=array();
    $long=array();
    while($points = sqlsrv_fetch_array($result)) {
    $lat[] = $points['gps_lat'];
    $long[] = $points['gps_long'];
    }


    $latLongSize = sizeof($lat)-1;

for($i=0; $i<=$latLongSize; $i++){ ?>

    var marker<?php echo $i; ?> = createMarker(new GLatLng(<?php echo $lat[$i];?>, <?php echo $long[$i]; ?>));  
        map.addOverlay(marker<?php echo $i; ?>);
