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。
