Codeigniter: multifile_array upload helper

If you need to use multiple files for upload in a form, but using array names (like files[]) with Codeigniter is not possible. Besides, $_FILES schema is not compatible with $this->upload->do_upload().
With this helper you can use this kind of names for make it possible. Only use array name for all files in a form and use the helper:

In view
<form...
<input type="file" name="f_file[]">
<input type="file" name="f_file[]">
...
</form>

In controller

$this->load->helper('upload');
multifile_array();
foreach ($_FILES as $file => $file_data)
  $this->upload->do_upload($file);
