How to use the refresh parameter in CodeIgniter redirect function

Question

Could sombody please tell me why do we need to use a "refresh" parameter for redirect function in codeigniter.

redirect('/index.php/it_inventory/get_users', 'refresh');

Answer 1

If you are familiar with core PHP header("Location:url_here") so this might be a new addition in your knowledge that redirection using header with the following syntax is also possible which is used in CI. When you pass the second argument refresh so the follow line works. And its optional. header("Refresh:0;url=".$uri)
