"<tr><td>" . $line["cdt"] . "&nbsp;</td>" .                 "<td>" . $line["username"] . ":&nbsp;</td>" .                 "<td>" . $line["msg"] . "</td></tr>";      }      $msg=$msg . "</table>";       echo $msg;

you can apply multiple order by in filed using comma

so instead of 

order username , id

use

 order username,id

also stop using mysql deprecated. can use mysqli or pdo
