Tried URI::uri_string() but can\'t get it to work with the base_url.
URL: http://localhost/dropbox/derrek/shopredux/ahahaha/hihihi
Returns: dr
Try to use "uri" segments like:
$this->uri->segment(5); //To get 'ahahaha'
$this->uri->segment(6); //To get 'hihihi
form your first URL...You get '' from second URl also for segment(5),segment(6) also because they are empty.
Every segment function counts starts form localhost as '1' and symultaneous segments
