Difficulty with two Uri segments

Question

They are trying to create the url, where the first segment is the user and the second is his file, e.g.: http://www.exemplo.com/joao/bola

Controller

public function user() {

    $user_url = $this->uri->segment(1);

}

^ This would return the profile with all the files: http://www.exemplo.com/joao

public function arquivo() {

    $arquivo_url = $this->uri->segment(2);

}

^ That the specific file: http://www.exemplo.com/joao/bola

Routes

$route['(:any)'] = 'home/user/$1';
$route['??'] = 'home/arquivo/$1';

Answer 1

Already getting the solution would be something like

$route['([^/]+)'] = 'home/user/$1';
$route['(:any)/(:any)'] = 'home/arquivo/$1';
