Just an idea, someone who's done it may know better.

- Have your original PHP store it's "status" information in a Session
variable says $_SESSION["status_data"] which is updates as it runs

- Have a timer on the Javascript side which creates a 2nd Ajax call
to a new getstatus.php, which then reads the status from the session and
sends back to the browser in this 2nd Ajax call.

Not done much Ajax, I am assuming you can make another ajax call whilst
one is currently running??

You might need to send the PHP session id back to the server when you
call getstatus.php, not sure.

Let us no how you do :)
