之前它运作良好。我没有做任何事，因为我不是那个制作代码的人。我唯一做的是将文件复制到一个新文件夹，但这两个文件都不起作用。在数据库中，我确实修改了一些但不在该程序正在使用的数据库中的数据库。

2 个答案:

答案 0 :(得分：3)

include "client_header.php";

您缺少此文件，因此可能会抛弃其余代码。您可能已将这些文件移动到不同的目录，更改include以允许更改目录。

代码中还有其他include，所以也要更新它们。

//编辑

检查原始来源，正如您所说这是其他人的代码，可能会有副本存在。 include命令表示client_header.php文件可用，可以在同一文件夹中，也可以作为PATH的一部分。有关详细信息，请参阅Php include文档和notes on include_path。

唯一的另一种可能性是这些错误之前存在但由于php设置而不可见。

答案 1 :(得分：0)

您移动了脚本，因此您需要更正包含路径：

include "client_header.php";

这是期望当前目录中的include，因此如果您将其移动到子目录，则可以在其前面添加../或为其指定绝对路径。
