CodeIgniter - print custom values in request header

Question

How can I print the values set in the header of a received request using CodeIgniter?

I tried print_r($_SERVER); which doesn't help me. I'm hoping there's a different way using CI.

Answer 1

Simply use,

$this->input->request_headers();

Answer 2

If you are sending values from form submit,

$_REQUEST will help you

or

    $this->input->post();
    $this->input->get();
