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

Actually force_download("file-name", $filepath);
Nothing you have written after this piece of code will be executed, because force_download method has a header and an exit call.

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

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);

回答2:

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

Use unlink('filename');,you will not use filepath only use filename.

回答4:

Use base_url() path for download the file and use FCPATH for unlink the file(absolute path to the file)

public function download($id)
    {
     $this->load->helper('download');
        $filepath = "url/" . $id;  // eg : base_url()."/".$id;
        force_download("file-name", $filepath);
    //    ignore_user_abort(true);
       $filepath2 = "url/" . $id;  // eg : FCPATH."/".$id;
        unlink();

    }
