在使用pbootcms的时候，很多时候会用到数据库，但是pb的数据库是.db文件，所以就很麻烦。
没有现成的可视化页面可以查看数据库，因此，这里开发了一个php在线查看的php可视化页面。
这样会方便许多。
如何使用？
在db文件的文件夹中，创建一个php，将下面代码放进去，修改自己的数据库名称，然后访问php文件即可使用。
已改进，可以查看多个db数据库
<?php
// 扫描当前目录下的所有.db文件
$db_files = glob("*.db");
$current_db = $_GET['db'] ?? ($db_files[0] ?? '');
// 分页参数
$per_page = 20; // 每页显示记录数
$page = isset($_GET['page']) ? max(1, intval($_GET['page'])) : 1;
$offset = ($page - 1) * $per_page;
