Problem with fsockopen() and IRC

[Anon]

I have make a small modul to irc...... :
<?php
$sock = fsockopen("gizeh.memphisnet.org", "6667");
$wn = rand(1,99);
fputs($sock,"NICK moulaf[$wn]\n");
fputs($sock,"USER K moulaf[$wn] gizeh.memphisnet.org :realname\n");
if(ereg("^[0-9]+$", $match[1]))
$done = 1;
else
{
// this might have been a PING message, check for it
if($match[0] == "PING")
{
// yes it was a PING, reply with a PONG
irc_put_message("PONG $match[1]");
}
else
{
if($match[0] == "ERROR")
{
return(0);
}
}

		// this wasn't an important server message, get the next one
		// by doing another iteration
	}

fputs($sock,"PING :gizeh.memphisnet.org\n");
fputs($sock,"PONG :gizeh.memphisnet.org\n");
while (!feof($sock)) {
$arf = fgets($sock, 1024);
echo "$arf<br>";
}
fputs($sock,"LUSERS\n");
fclose($sock);

?>

When I launch, the modul respond to me :
:gizeh.memphisnet.org NOTICE AUTH : Recherche de votre hostname...
:gizeh.memphisnet.org NOTICE AUTH : Hostname trouvé (cached)
