One problem you're going to run into is that by using
$_SERVER['REMOTE_ADDR'] oftentimes, you'll end up with just the IP.
I wrote the below to give me the hostname, which generally gives you
the ISP information too, to fix a problem on a project I was doing.
If it won't resolve to a name (which does happen sometimes for
machines behind corporate firewalls), I just displayed "No Reverse DNS"
<?php
$pingResults = shell_exec('ping -a ' . $_SERVER['REMOTE_ADDR']);
$temp = explode("\r\n",$pingResults);
preg_match("/^Pinging\s([a-zA-Z0-9.]+)/", $temp[1], $hostname);
if ($temp[4] == "Request timed out.")
$latency = "Unknown";
else
$latency = $temp[4];
?>
Hostname: <?php if (!$_SERVER['REMOTE_ADDR'] == preg_match("/^[a-z.]+/i",$hostname[1])) echo "No Reverse DNS"; else echo $hostname[1]; ?>
Latency: <? echo $latency; ?>
Geez, it's amazing when you dig back through old code you realize how
much your coding skills sucked back then! <grin>
