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; }
