Using site_url() in Codeigniter without getting a ? in the generated URL -

i trying use site_url() in codeigniter, every time put in parameters (for example site_url('controller_name'); url in link looks this:

http://{mysite}/index.php?controller_name

instead of think should getting is:

http://{mysite}/index.php/controller_name.

i using echo site_url() syntax in link on webpage far have been unsuccessful.

i think problem config file check config file

$config['uri_protocol'] = 'query_string';

then change in this

$config['uri_protocol'] = 'auto';
