title: switching language codeigniter
body: <p>I am a new coder. I am doing a work where I have to provide the option to the users to select their preferred languages by just clicking on a language they like.
  my question is that do I have to make two different controllers(e.g-for two language)
  and the similar number of 'two' functions or view files for each language?
  or is there any alternative ways to do this?
  it is like the site:

  give me suggestions please.</p>
