how to get database value into javascript google map

Question

i know there is the same question like mine but i still don't understand...

i want to make a google map with value in my database there are 3 value in my database: name, lat, and lon.

and i want to get this value and add this into my javascript.

here is my google map script (stil fresh from w3school) :

<script>

var myCenter=new google.maps.LatLng(51,508743,-0,12085);

function initialize()
{
var mapProp = {
  center:myCenter,
  zoom:5,
  mapTypeId:google.maps.MapTypeId.ROADMAP
  };

var map=new google.maps.Map(document.getElementById("googleMap"),mapProp);

var marker=new google.maps.Marker({
  position:myCenter,
  });

marker.setMap(map);
}

google.maps.event.addDomListener(window, 'load', initialize);
</script>

i have read this question :Getting database values in Javascript variable dynamically .

but still dont understand how it works, what do i need to add and what do i need to change. please help

fetch the data from database and replace your value with variable as below var myCenter=new google.maps.LatLng(<?php echo $lat;?>,<?php echo $lang;?>); — Mukesh Ram

In which language?

In PHP you have to just use your variables with db table column values in place of long and lat.

e.g. and

var myCenter=new google.maps.LatLng(,);

Let me know if you want the multiple maps with in the loop.
