Index.php文件如下：

<?php 
$path = "DB/"; //定义路径 
$dr = opendir($path); //打开目录 
while($filen = readdir($dr)) //循环读取目录中的文件 
{ 
  if($filen != "." and $filen != "..") 
  { 
    $fs = fopen($path.$filen, "r"); 
    echo "<B>标题：</B>".fgets($fs)."<BR>"; 
    echo "<B>作者：</B>".fgets($fs)."<BR>"; 
    echo "<B>内容：</B><PRE>".fread($fs, filesize($path.$filen))."

"; echo "

"; fclose($fs); } } closedir($dr) //关闭目录 ?>

Post.php文件如下：

<?php 
$path = "DB/"; 
$filename = "S".date("YmdHis").".dat"; 
$fp = fopen($path.$filename, "w"); 
fwrite($fp, $_POST["title"]."/n"); 
fwrite($fp, $_POST["author"]."/n"); 
fwrite($fp, $_POST["content"]."/n"); 
fclose($fp); 
echo "留言发表成功！"; 
echo "<a href="Index.php" mce_href="Index.php">返回首页</a>"; 
?>
