title: CodeIgniter App - How to update session data of all devices if user information data was changed from another device
body: <p>So I have come across a problem.</p>
  
  <pre><code> 1. I log into website using my user information on my desktop.
   2. My sessions are set within the desktop.
   3. I log into website using a smartphone. (Now there are 2 devices logged in.)
   4. My sessions are set within smartphone.
   5. I change my user information in user settings page using my desktop.
   6. Database is updated.
   7. Sessions are updated on desktop, but not on phone.
  </code></pre>
  
  <p>How do I fix it? Should I use CodeIgniter's database driver for sessions? Would that even matter?</p>
  
  <p>Thanks.</p>
