它以前工作得很好。我没有做任何事情，因为我不是编写代码的人。我所做的只是将文件复制到一个新文件夹，但两个文件都不起作用。在数据库中，我确实修改了一些，但不是在该程序正在使用的数据库中。

include "client_header.php";

您缺少此文件，因此它可能会丢弃其余代码。您可能将这些文件移动到不同的目录，更改include以允许目录更改。

代码中还有其他include内容，因此也要更新它们。

// 编辑

检查原始来源，因为你说这是别人的代码，可能有副本存在。该include命令指示该client_header.php文件将可用，无论是在同一文件夹中还是作为PATH. 有关更多详细信息，请参阅PHP 包含文档和有关 include_path 的注释。

唯一的另一种可能性是这些错误之前存在，但由于 php 设置不可见。

您移动了脚本，因此您需要更正包含路径：

include "client_header.php";

这期望包含在当前目录中，因此如果您已将其移至子目录，则可以为其添加前缀../或为其提供绝对路径。
