我已经为在线游戏上的招聘申请编写了表格，但当我实际将代码放在网站上时遇到了一些问题。在我的本地 apache Web 服务器上运行此操作运行良好，但在在线 LiteSpeed Web 服务器上执行此操作似乎不起作用。代码中是否存在无效内容？

我已经设置了代码来检测任何错误(我已从下面的示例中删除了该错误)，但除了 undefined variable 之外什么也没有出现(在本例中这很好)。

是的，我在网站版本上运行 PHP。

最佳答案

请添加

var_dump(file_exists('includes.php'));

就在

之前 
require('includes.php');

如果找不到文件，则 require 删除任何进一步的代码
