推荐答案

我遇到了同样的情况。因此，我只想分享以下信息，以帮助有需要的人。

I have came across same situation. So i just want to share the following information if that helps people in need.

实际上
force_download（ file-name，$ filepath） ;

在这段代码之后您将不会执行任何操作，因为force_download方法具有 header 和 exit 调用。

因此，如果要删除正在下载的文件，可以在调用 force_download 方法之前将其删除。

So if you want to delete file which is being downloaded, you can delete it before calling force_download method.

有些人会怀疑我们在下载文件之前如何删除它。实际上，force_download方法中的第二个参数实际上是正在下载的文件的内容。一旦有了该文件，就不需要该文件。

Some people will be having a doubt like how can we delete a file before downloading it.Well actually the second parameter in force_download method is actually the content of the file being downloaded. Once you have that you do not require the file.

$file_content = file_get_contents($file_path); // Read the file's contents
if(file_exists($file_path)){
    unlink($file_path);
}
force_download($filename, $file_content);
