所以目前我有一个用户提交的 html 表单，然后创建一个文件并使用 PHP 给出一个随机名称，我将如何获取用户创建的文件并重命名它，然后为其创建下载链接？
在简短的步骤中，用户填写表单，单击提交，创建具有随机名称的文件(例如434242.txt(，显示下载链接页面，用户单击下载链接，他们创建的文件作为新文件名下载到他们的计算机(例如customname.txt(。
我不知道我是如何做到这一点的，所以任何指导都会很棒！
这是我的 html 表单;

您需要在 httpdocs-dir 中创建文件以使其可下载。在我看来，您的文件是在目录"temp/tmp/"中创建的，它应该在您的 http 目录中。
因此，您可以使用
echo '<a href="temp/tmp/server'.$id.$ext.'">download</a>';
在 php 文件中的 fclose(( 之后的末尾。
[编辑]如果要强制下载而不是查看文件，则需要在 apache 上启用mod_headers：
以根用户身份登录：
# a2enmod headers
# /etc/init.d/apache2 reload
更改主机的 http.conf(名称和位置取决于 Linux 发行版和服务器配置(：
AllowOverride All
在下载目录中创建一个 .htaccess 文件：
<FilesMatch "'.(?i:txt)$">
ForceType application/octet-stream
Header set Content-Disposition attachment
</FilesMatch>
如您所见，强制下载文件而不是查看，对于没有经验的用户来说有点棘手。最好用这样的文本标记下载链接：
(要下载文件，请按鼠标右键 ->保存链接(
当然，您可以在下载目录中创建.htaccess，并希望mod_headers已启用，并且默认情况下将AllowOverpred设置为"全部"。请注意，.htaccess只是更改.txt文件。对于其他扩展，您需要对其进行调整。
