PHP Port Scanner

Hi all,

I am trying to find some code that I can use on my site to enable my
visitors to do a basic portscan of their computers. My site is a
security site and I want to show my visitors that their machines might
be wide open, or at least how to tell if they are protected.


I have found several examples, some as basic as:

<?
$host = "[Some IP Address]";
for($i=0;$i<500;$i++) {
$fp = fsockopen($host,$i,$errno,$errstr,1);
if($fp)
{
echo "port " . $i . " open on " . $host . "\n";
fclose($fp);
}
else
{
echo "port " . $i . " closed on " . $host . "\n";
}
flush();
} //end for
?>

The problem, is it is really, really slow. Is there a faster way to do
this? I think I need to find another solution that uses Threading.

Any help would be appreciated
