我希望你做得很好。我遇到了无法将数据插入数据库的问题。发生这种情况的原因有很多，所以请不要将其视为重复的问题。我检查了我的代码。对于一个表，它会保存数据，但是对于此表。它显示找不到相同的页面，并且没有数据保存在本地数据库中。我希望你能帮助我们。提前致谢。 :) 以下是一些有用的代码：
<?php
include 'Header.php';
?>
<style>
#first {
//margin-right: 100%;
//clear: both;
}
#first > img {
display: inline-block;
//float: left;
}
#first > p {
//float: left;
display: inline-block;
//margin-left: 60px;
//margin-bottom: 120px;
}
</style>
<!-- Post content here -->
<!-- Then cmments below -->

$dbc = $db->getConnection();
$display = 10; //number of records per page
$pages;
if(isset($_GET['p']) ) //already calculated

$records=$row[0];
if($records > $display ) //calculate the number of pages we will need

我在登台网站上工作时遇到过这种问题，因为虚拟主机可能有不同的限制和严格限制。现在我所做的就是更改文件名，例如：
类名应与文件名匹配，因为它区分大小写。
Comment.php
class Comment extends DBConn {
function __construct () {
parent::__construct ();
}
//code here..
}
