Controller Names with Dashes or Underscores?

[eluser]e-mike[/eluser]

Code:

<?php
class MY_Router extends CI_Router
{
    function _set_request($segments = array()) {
        parent::_set_request(str_replace('-', '_', $segments));
    }
}
?>

Put this file MY_Router.php inside /application/libraries (CI1) or /application/core (CI2)
Remember that this will effect all segments, not only module, controller and method.

Alternative to this extend is to add each segment to router.php
$route['this-is-a-module-or-controler'] = 'this_is_a_module_or_controller';

As you can see the extend method would be easier to use. You can choose to make the function also to handle only the first two or three segments so that the other segments are not affected with the _ replacement.
