Not without doing a <meta refresh> after each one. Once data is sent to the
browser, it's stuck there. I guess an ugly way to do this would be to use
Javascript to hide your previous output as your new output comes in. This
would be way ugly, though.

That didn't seem to work

$x = 1;
while ($x < 20) {

echo $x.'<br>';
echo $data.str_pad(" ", 300);
flush();
echo "<meta refresh>";
$x++;
sleep(1);


}

Still lists it one by one instead of in place of eachother...

<meta refresh...> is a client side hack for achieving what we can do
server side.
In HTML, using <meta http-equiv... is equivalent to sending the same
header directly to the client.

So, writing the following HTML:
<meta http-equiv="refresh" content="0;url=http://www.nowhere.com">

is equivalent to this PHP call:
Header("refresh","0;url=http://www.nowhere.com");

The latter is, of course, usually invisible in the source code
