Answer 1

$domain = parse_url("www.domainnames.com");
    $host = $domain['host'];       
     $exp  = explode('.' , $host);        
                if(isset($exp[2])){        
                $domainname = ($exp[1]);
                }else {           
                    $domainname = ($exp[0]);
                }
                $a []= $domainname;  

      $uniquenames = (array_unique($a));    
      print_r($uniquenames);
