php - CodeIgniter: How to get Controller, Action, URL information

Question

I have these URLs:

• http://backend.domain.com/system/setting/edit/12
• http://backend.domain.com/product/edit/1

How to get controller name, action name from these URLs. I'm CodeIgniter newbie. Are there any helper function to get this info

Ex:

$params = helper_function( current_url() )

Where $params becomes something like

array (
  'controller' => 'system/settings', 
  'action' => 'edit', 
  '...'=>'...'
)

Answer 1

You could use the URI Class:

$this->uri->segment(n); // n=1 for controller, n=2 for method, etc

I've also been told that the following work, but am currently unable to test:

$this->router->fetch_class();
$this->router->fetch_method();
