首先是保证文本文件可读写，在文件准备写入之前，我们所要做的是处理好用户留言！
这项工作可以在提交表格前进行，我们将得到的数据各项用特定的符号分开，比如说用&号，值得说明的是如果提交的数据中如果也包含有特定字符，那我们只好将他转化成其他形式，这一点各位自有办法；
如是我们得到数据形如：
$str=”aaaaa&bbbbb&ccccc&ddddd”;
在将数据写入文件前我们加上
$str=$str.”\r\n”

然后执行：
$fp=fopen("txt/mytxt.txt","a");
fwrite($fp,$txt);
fclose($fp);

这样我们写入的数据位于文件末尾部分
如何让最新的留言出现在留言板的首位？
数据有了以上的处理，就好办了，
$date=file(“txt/mytxt.txt”);
$n=count($date);
for ($I=$n;$I>0;$I--){
$str=explode(“&”,$date[$I])
.
//将得到的$str数组各项输出.
.
}

这样最新插入的留言就保持在首位。

//用函数读出数据表内容放入二维数组
//动态sql语句
//以读出点击次数表为例。

function list_hit($fields,$where,$order,$direction,$limit,$conn)
{
if ($fields=="") {$fields="hit_id,banner_id,hit_ip,hit_time";}
if ($order=="") {$direction="";}

$sql="select $fields from hit $where $order $direction $limit";
//echo $sql;
$res=mysql_query($sql,$conn);
$i=0;
$list_hit[$i]["rows"]=mysql_num_rows($res);
$i++;
while($rs=mysql_fetch_array($res))
    {
    $list_hit[$i]["hit_id"]=$rs["hit_id"];
    $list_hit[$i]["banner_id"]=$rs["banner_id"];
    $list_hit[$i]["hit_ip"]=$rs["hit_ip"];
    $list_hit[$i]["hit_time"]=$rs["hit_time"];
    $i++;
    }
return $list_hit;
}
