Have the top of the page do a $msg = $_GET['msg']; and have the php
doing the processing send a ?msg=whatever_the_message_is after the page
name in the header("Location:......) directive.

Then, on your page you process that value using normal HTML (for example
as a textarea with readonly properties) or as the input to an inline
javscript that will put up an alert if there is some value received and
not be invoked at all if $msg is not set.

What I do is have a message at the top of the page, no surrounding box,
which is invoked only if $msg is set:

if (isset($msg)) echo $msg;

or

if (strlen($msg) > 0) echo $msg;

Of course you can put all that inside a <span></span> where you will
define print properties such as color, size, alignment, etc.
