Default configuration already has url like

Code:

http://www.example.tld/index.php/controller/method/param1/param2/param3

It is set in: application/config/config.php file with setting correct parameter ($config['enable_query_strings']) to FALSE value.
I would warmly suggest you to read user guide. This your question is answered in the first topic there.
