greetings

you can prefilter data. example use 

$user_comments=array(); $other_comments=array();  while($row = mysql_fetch_assoc($result)) {     if($row['user']==$current_user)    {         $user_comments[]=$row;    }    else   {         $other_comments[]=$row;   } } $comments=array_merge($user_comments,$other_comments);

then can display information way want to.
