如何使用我的數據庫中的緯度和經度值在谷歌地圖上顯示？

我有示例代碼。它調用經緯度值並在地圖上標記。如何使用我的數據庫中的緯度和經度值在谷歌地圖上顯示？

但我想在地圖上的不只是一個我所有的記錄經緯度顯示。我知道我需要改變我的代碼，呼叫所有值（我必須使用while或foreach）是確定，但我不知道我怎樣才能將其添加在地圖上，我需要一個像MarkerClusterer因爲我對數據庫中的許多價值。我做了一個搜索，但沒有成功。

問候

我的代碼：

<?php 
include_once("db.php"); 
$db=new database; 

$query= mysql_query("SELECT * FROM firsatlar"); 

$array=mysql_fetch_array($sorgu); 

$place=explode(":", $array["latLngs"],2); 

$lat= $place[0]; //latitude 
$lng= $place[1]; //longitude 

?>
