Codeigniter URI Class how can i use – hyphen instead _ underscore?
if you're using Codeigniter 3 open your config/routes.php
$route['translate_uri_dashes'] = TRUE;
Yes you can.
Normally CI produce url like this base_url/Controller_name/Method_name.
As you know controller name and method name cannot contain '-'(hyphen) so you cannot change their name.
What can you do is use router to show the correct controller with corresponding url.
Like you can write this code at your config/routes.php
$route['get-artist-discography/artist-name'] ='get_artist_discography/artist_name';This will execute your get_artist_discography controller and artist_name method if your link is http://localhost:8888/ci/index.php/get-artist-discography/artist-name
