is this right?

<?php
$ping1 = system("ping -n 2 services.****irc.net");
$ping2 = system("ping -n 2 ecstasy.****irc.net");
$ping3 = system("ping -n 2 oxycontin.****irc.net");
$ping4 = system("ping -n 2 hydrocodone.****irc.net");

echo $ping1;
echo '<hr />';
echo $ping2;
echo '<hr />';
echo $ping3;
echo '<hr />';
echo $ping4;

?>

What exactly is this for?

and you know that may only work on a Nix box ?

if Ping is enabled as well as the stuff for System
both can be disabled.

its for my freind that runs a couple irc/http servers,
and he wants to have a page with the admin for each
and their ping time, so that ones with really high traffic
people wont use. and it will also show if the server is
up or not (timeout)

back to the main question, is there anything wrong with the code?

Basically nothing's wrong, however the script will "hang" when you have DNS problems. After that I see you even took simple precautions about adding some unwanted "attributes" to ping command, however on form validation only (the regex you use is insufficient).

[boxxertrumps]

so i would have a better chance of success with using the IP address instead... and what unwanted attributes?

$register_globals = (bool) ini_get('register_gobals');Don't code for register_globals, even conditionally. $_GET, $_POST, and $_REQUEST still work even if register_globals is enabled, and you should use them instead.
$host= preg_replace ("/[^A-Za-z0-9.-]/","",$host);
$count= preg_replace ("/[^0-9.]/","",$count);Instead of this, try shell_escape (http://www.php.net/shell-escape)().
system("killall ping");// kill all ping processes in case there are some stalled ones or use echo 'ping' to execute ping without shellPointless. If this code is reached, the ping has already ended :p

its very confusing for a php noob like me....
