PHP <--> Javascript

[Anon]

Inside php source code :
<?
global $abc;
$abc = "abc";
?>

So in Javascript:
<script language="Javascript">
<!--
var abc;
alert(abc);
-->

What's happen?
In fact, I want to write a html page which can display a "alert" box.
What function of PHP can do this like "alert"??

Thank You

Try this:

Inside php source code :
<?
global $abc;
$abc = "abc";
?>

So in Javascript:
<script language="Javascript">
<!--
var abc = <?print $abc;?>;
alert(abc);
-->

You have to actually use php within the Javascript
