mysql_query inside an OnUnload Function

I've got a Java onUnload function. Is there any way to open PHP inside this Java function and let's say to start a mysql_query?

I tried it in a lot of variations, always with a structure like that in mind:

<head>
<title>
</title>
<script language="java">
function exit()
{
<? mysql_query("....."); ?>
}
</script>
</head>
<body onUnload="exit()">
</body>

By now I guess that I'm simply causing some Java PHP mismatch! Am I ?

Any help would be appreciated!

Try opening a window with the Javascript that loads a PHP page into it that is making the query.

PHP code in the middle of a JS script will conflict with the JS. The js will try to run the php code and cause an error.

Thanks for this solution. It works out well ...
