How to repeat this script, using POST data every 30 seconds or so...?

Hi,

I've got this script attached, which checks if a server is responding or not, like "ping example.com"...

I want to modify this script so that every 30 seconds, it'll repeat, to continually recheck the domain.

I thought about using sleep(), but that'd time the script out eventually, and I think using a meta refresh or javascript refresh wouldn't resubmit the post data...

Any thoughts?

Thanks.

<?php
// Function to check response time
function pingDomain($domain)
{
    $starttime = microtime(true);
    $file = @fsockopen($domain, 80, $errno, $errstr, 10);
    $stoptime = microtime(true);
    $status = 0;
    if (!$file)
        $status = -1; // Site is down
    else {
        fclose($file);
        $status = ($stoptime - $starttime) * 1000;
        $status = floor($status);
    }
    return $status;
}
?>

if (isset($_POST['submitBtn'])) {
    $domainbase = (isset($_POST['domainname'])) ? $_POST['domainname'] : '';
    $domainbase = str_replace("http://", "", strtolower($domainbase));
    echo '<table>';
    $status = pingDomain($domainbase);
    if ($status != -1)
        echo "<tr><td style='padding:10px;background:#cfc;border:1px solid #3c3;'>http://$domainbase is UP ($status ms)</td><tr>";
    else
        echo "<tr><td style='padding:10px;background:#fcc;border:1px solid #c33;'>http://$domainbase is DOWN</td><tr>";
    echo '</table>';
}

Whoa there horsey, I think AJAX is a bit heavy for this? Is there no simpler way? it's just a little tool for me and a couple of the guys here to use now and again when servers go down... :(

If you think that's the only way, it seems a bit convoluted, so might just keep hitting F5...

Thanks guys. I agree the AJAX way would be better, but the simple JS will do for this. Thanks.
