title: Rewrite the url using CodeIgniter
body: <p>I read a lot of forum topics but  I did not found any answer which meets my needs.</p>
  
  <p>I am running a blog system and my current urls for each article look like: <code>www.example.com/controller/method/id</code>.  However, for each article I have a title stored in a database, and would like to use that title in the url, so it would look like this: <code>www.example.com/title</code></p>
