java script within php

is it possible to insert a java script within php scripts or tags.

say

php:

<?php
script = java script;
(java scripts here)
?>

I'm not quite sure what your asking. Just remember, that JavaScript is executed by the browser on the user's computer and PHP is executed by the server before the user sees the page. So, you cannot embed JavaScript in a PHP document and have them execute sequentially, but you can use PHP to create JavaScript.

yes, it is possible.
example:
[highlight=php]
<?
echo("<script language=javascript>n
window.open('add_new.php','NewWindow','width=100,h eight=100');
</script>");
?>
