title: How can I use CodeIgniter ACL library?
body: <p>How can I implement an ACL library? What is the best way for using ACL for user roles? In standard PHP, I'd write code like this:</p>
  
  <pre><code>if (userTypeId == 'Admin') {
    hello Admin
  } else if (userTypeId == 'Member') {
     hello member
  }
  </code></pre>
  
  <p>How would you do this using CodeIgniter?</p>
