Using a Query String with Segmented Controller/Method URLs in CodeIgniter

CodeIgniter has some awesome segmented URL functionality baked into its core, but sometimes you want to be able to do things like this:

http://my-domain.com/my_controller/my_method?some=more&sweet=stuff

You can do so easily by doing the following:

1. In config.php change:
• $config['enable_query_strings'] to TRUE
• $config['uri_protocol'] to 'PATH_INFO'
2. In your controller:
• Fetch the query string using $this->input->get('some');
  (this example corresponds with the above URL)

And that's all folks! It works when a query string isn't present, it works with any number of query string variable pairs, it works with method parameters (e.g. /my_controller/my_method/my_param?some=more). It just works! Sweet, eh?
