PHP & Javascript -- probably a simple question

[dico]

Hi There,

I am wondering how I can use php variables in javascript code.

For example, I am playing around with google maps and here is a piece my code:

<script type="text/javascript">
var point = new GPoint(-53.123901, 36.231747);
</script>

However, I would like it to work like:
<?
$lat=50;
$long=40;
?>

<script type="text/javascript">
var point = new GPoint($lat, $long);
</script>

However, that doesn't seem to work. Any suggestions?

Thanks,

if it's a simple one or the other choice, then hardcode your points into the javascript variable. Ultimately, your going to be plotting a number of locations. And you'll only be wanting to plot to the visible area of the maps, so some logic will be involved, as will storing/retrieving your data.

The approach then becomes easier to perform the http reguest which provides user data to a php script, which in turn performs the required logic, fetches data and prints it back to the javascript for overlay display.

var url = "your php script url";
var request = GXmlHttp.create();
request.open("GET", url, true);
request.onreadystatechange = function() {

Google maps api documentation provides many examples.
