how to use latitude and longitude value from my database to show on google map?
Question
I have sample code. It is calling latitude and longitude value and marking it on maps.
But i want my all record latitude and longitude show on maps not just one. I know i need change my code for call all value (i must use while or foreach ) it is ok but i don't know how can i add it on map and i need like MarkerClusterer Cause i have many value on database. I did a search but did not succeed.
Regards
My Code:
<?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
?>

Query your database with AJAX. Loop through the results to create each marker. There are plenty of examples around. Then you can refer to the MarkerClusterer documentation http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/docs/examples.html to create your marker clusters.

一个简单的解决方案是使用php中的标记集群： http : //www.appelsiini.net/2008/introduction-to-marker-clustering-with-google-maps 。
