Yeah, use php function parse_url (http://php.net/parse_url), it will help you.

UPDATE based off (currently third answer) - Remove domain extension

$url = 'php.co.uk';
preg_match('/(.*?)((?:\.co)?.[a-z]{2,4})$/i', $url, $matches);

print_r($matches);

IGNORE FOLLOW - Bad practice, but still explains working of explode.

See when you explode and you use '.', it finds it twice in .co.uk. So if you where to echo both $host[1] & $host[2] you would get co uk respectively.

So as a partially complete (not sure what your end game is) solution:

Solution:

$url = "domain.co.uk";

$host = explode('.', $url);
$first = true;
foreach($host as $hostExtension){
  if($first){
      $first = !$first;
      continue;
  }
 else{
      echo $hostExtension .'<br>';
  }
}

To be clear though, the other answers explain how you should be parsing the URL. I just merely thought to explain why (answering the question) your code was doing/return what it was and how you would get your intended result.
