If you combine yp_first and yp_next you can get the whole list:
function yp_list($domain, $map) {
   $entry = yp_first($domain, $map);
   $key = $entry ["key"];
   $yplist[$key] = $entry ["value"];
   
   while ($entry) {
      $entry = yp_next($domain, $map, $key);
      if ($entry) {
         $nextkey = key ($entry);
         $yplist[$nextkey] = $entry[$nextkey];
         $key = $nextkey;
      }
   }
   return $yplist;
}
