title: CodeIgniter-Multiple Sub Class Prefix
body: <p>Is it possible to define multiple sub class prefix. Now the prefix is written in following format.</p>
  
  <pre><code>$config['subclass_prefix'] = "MY"; 
  </code></pre>
  
  <p>Here I can create custom controller <strong>MY_Controller</strong>, which is appended with prefix "MY".</p>
  
  <p>Here I want to create another custom controller called <strong>MY_AdminController</strong> along with MY_Controller. How do I define my subclass prefix in this situation.</p>
