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;


}
