Array Issue help please

["Dave Carrera" <dave@davecarrera.com>]

Hi All
I have nearly got this working but it dose not seem to loop though or
return the result
 
I have done something wrong and I ask one of you coders that are much
cleverer that I to glance over my code to see the obvious mistake / s.
 
Thank you in advance for any help

// Start of my code
 
if(isset($_POST[domain])){
$uswhois = "whois.networksolutions.com";
$ukwhois = "whois.nic.uk";
$arr =
array(".co.uk",".org.uk",".plc.uk",".ltd.uk",".me.uk",".com",".net",".or
g");
echo "Top Level Domains: <br /><br />";
 $domname = $_POST[domain];
  while(list(,$tld)=each($arr)) {
   if(($tld == ".com") || ($tld == ".net") || ($tld == ".org")){
   $whois = $uswhois;
   $linenumber = 8;
   }
   else
   {
   $whois = $ukwhois;
   $linenumber = 2;
   }
