php＋dbfile开发小型留言本
board.php用来存储数据，可以先在里面添加了一条留言纪录。
代码
<?php $Board=array( array(1081410332,'测试','测试留言本','http://www.phprm.com') ); ?>
index.php是留言显示和提交页面。
代码
<?php
header('Content-type:text/html;charset=utf8');
require_once ('board.php');
function htmlencode($content) {
$content = htmlspecialchars($content);
$content = preg_replace("/\r/i", "<br />", $content);
return $content;
}
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$configpath_parts1 = pathinfo($_SERVER['SCRIPT_FILENAME']);
$time = time();
$name = $_POST['name'];
if(preg_match("/^[\\w-]+(\\.[\\w-]+)*@[\\w-]+(\\.[\\w-]+)+$/i", $_POST['url']) || $_POST['url'] == '')
{
$url = $_POST['url'];
}else{
$url = 'http://' . htmlspecialchars(preg_replace("/https?\:\/\//i", '', $_POST['url']) , ENT_QUOTES);
}
$info = htmlencode($_POST['info']);
if ($name != '' && $info != '') {
$Board[] = array(
$time,
$name,
$info,
$url

next($Board);
}

?>[Ctrl+A 全部选择 然后拷贝]
config.php中存放的是管理留言本的密码，把密码放在单独一个文件中方便修改。 代码拷贝框
[Ctrl+A 全部选择 然后拷贝]
admin.php是管理页面，功能很简单，只能删除留言。在删除时需要输入管理密码，管理密码存放在config.php中。 代码拷贝框
