CodeIgniter -> Get current URL relative to base url

Question

Tried URI::uri_string() but can't get it to work with the base_url.

URL: http://localhost/dropbox/derrek/shopredux/ahahaha/hihihi
Returns: dropbox/derrek/shopredux/ahahaha/hihihi

but http://localhost/dropbox/derrek/shopredux/ just returns an empty string.

I want the first call to return "ahahaha/hihihi" and the second to return "". Is there such a function?

Answer 1

// For current url
echo base_url(uri_string());

Answer 2

If url helper is loaded, use

current_url();

will be better
