下载 GPG 文件时出错 filesize() stat

Question

我的 PHP 程序应该将一些数据写入文本文件并使用 gnupg 加密该文件。当用户按下下载时，程序应下载扩展名为.GPG 的加密文件。

我可以成功加密和解密文件。但我在我的加密文件中看到 html 代码和错误。但是在我解密文件后它就消失了。但它仍然被认为是一个错误是吗？有人可以帮忙吗？

我的部分 HTML 代码：

问题已解决。刚刚意识到错误的文件夹路径不正确。我删除了下载代码中的文件夹路径：

$file='./uploads/' . $filename . '.gpg';

收件人：

$file= $filename . '.gpg';

谢谢大家！ :)
