$countries = array (
"london,united kingdom,",
"manchester,united kingdom",
"madrid,spain",

$lastcountry = '';

foreach($coutries as $id=>$country)
  {
  $cityset = explode(',', $country)
  if($ityset[1] == $lastcountry)
    {
    echo $cityset[0]."<br />";
    }
  else
    {
    $lastcountry = $cityset[1];
    echo "-".$cityset[1]."<br />".$cityset[0]."<br />";
    }
  }
