Refresh Widgets

Hello, I am currently designing a radio blog, and I found a plugin called IceStats.

I modified the icestats-display.php file to be this:

<?php
//Display IceCast Server Stats

	$server = get_option('icestats_server');
     	$iceport = get_option('icestats_port');
	$iceurl = get_option('icestats_url');
        $online = "<font color=green><b>ONLINE</b> </font><br />";
        $offline = "<font color=red><b>OFFLINE</b></font><br />";

        if($fp = @fsockopen($server, $iceport, $errno, $errstr, '1')) {
                fclose($fp);
                $ice_status=$online;
                echo "<br /><p><b>&nbsp&nbsp Stream Status:</b> $ice_status";
                $stats = file("https://" . $server . ":" . $iceport . "/status2.xsl");
                $status = explode(",", $stats[5]);
                $artist = explode("-", $status[5]);
                echo "<p>";
                echo "<b>&nbsp&nbsp Artist:</b> " . $artist[0];
                echo "<br />";
                echo "<b>&nbsp&nbsp Song:</b> " . $artist[1];
                echo "</p>";
		echo "<hr />";
		echo "<p>&nbsp&nbsp&nbsp <a href=https://" . $server . ":" . $iceport . "/" . $iceurl . " target=new><b>Listen!</b></a></p>";

         } else {

                $ice_status=$offline;
                echo "<p><b>Stream Status:</b> $ice_status";
        }

?>

I want it to refresh the radio stats INSIDE the Widget, so that it doesn’t bother the user.

I did some searches on google, and the only thing I could find was

<?php header('Refresh: 20');
?>

I tried, but it kept refreshing the PAGE. I want it to refresh the widget.
