I suppose it's UTF-8, as that's the default encoding for PHP as well as from the database. Its file extension will be .DAT, and I have already added it to config/mimes.php this way: 'DAT' => 'text/plain; charset=ISO-8859-1' Then if I try to download that string, using the download helper of Codeigniter (assume I have already loaded the helper) force_download('MYFILE

问题 Been struggling with this thing for hours now. Hopefully someone could help me out. Trying to get data from mysql based on first and last name.
