Is there a code that grabs the URL of a parent window of a popup?

I need a code that will grab the parent URL of a popup.
Does anyone know of one?

You could append the parent URL to the query string in JavaScript:

[code]<?php
$parent = "http://".$_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF'];
?>

window.open("http://www.example.com/?parent=<?php echo urlencode($parent); ?>","mywindow");[/code]

Then, on the popup page, grab that GET variable like this:

[code]<?php
$parent = urldecode($_GET['parent']);
?>[/code]
