本文实例讲述了php文件操作之小型留言本。分享给大家供大家参考。具体如下：
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))."</PRE>";
echo "<HR>";
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>";
?>

希望本文所述对大家的php程序设计有所帮助。
