This will append to a file, stored in custom/files/private, which will use the batch id as its filename. If the file does not exist, it will be be created. $batch is the array returned by $content is the string contents we wish to add to the file. $filetype is the ext of the file, which gives us a clue of the file type.

  }

  // Now, append to it...
  file_put_contents($filename, $content, FILE_APPEND);
