如何让数据按时间或者ID排序啊

 <?php
@mysql_connect("127.0.0.1","root","1s#876#$#$%Ss2")or die;    //链接数据库
@mysql_select_db("gamedb")or die;    //选择数据库
@mysql_query("set names 'utf8'");
$query = @mysql_query("select * from role_data")or die;    //查询‘yonghu’表中的所有记录
echo "<table border=1><tr align=center><th>ID</th><th>角色</th><th>对应帐号</th><th>等级</th><th>上线</th><th>下线</th><th>钻石</th></tr>";
$n=0;
while ($row = mysql_fetch_array($query))    //遍历‘yonghu’表中的数据，并形成数组
{
    $role_id = $row['role_id'];    //使用键获取数组中对应的值
    $role_name = $row['role_name'];
    $account_id = $row['account_id'];
    $level = $row['level'];
    $login_time = $row['login_time'];
    $logout_time = $row['logout_time'];
    $bag_yuanbao = $row['bag_yuanbao'];
    echo "<tr>";
    echo "<td>{$role_id}</td>";    //按照数据表的列在表格里输出对应数据
    echo "<td>{$role_name}</td>";
    echo "<td>{$account_id}</td>";
    echo "<td>{$level}</td>";
    echo "<td>{$login_time}</td>";
    echo "<td>{$logout_time}</td>";
    echo "<td>{$bag_yuanbao}</td>";
    echo "</tr>";
    $n++;
/*    if($n>14){
        return;
    }*/
}    
echo "<table>";
?>

你好，你得在 SQL语句中，加上排序 ，如 select * from role_data order by login_time 这是按时间排序 如 select * from role_data order by role_id 这是按ID排序

排序当然是通过SQL，order by来实现的。select * from 表 order by 字段（如ID）desc则为倒叙。把desc改为asc则为顺序，很简单很基础得sql语法。
