Codeigniter - 如何将选定的页码传递给url并相应地显示

Question

I am playing with pagination in codeigniter first time so having some difficulties so need help or guidance.

Here is my code which i am using and it is working perfect but getting pagination number like this:

Page 1: Getting 2 number in url (http://localhost/projectname/campaigns/2)
Page 2: Getting 6 number in url (http://localhost/projectname/campaigns/6)

I don't want to pass number like above behavior but expecting like this way:

Page 1: Set 1 number in url (http://localhost/projectname/campaigns/1)
Page 2: Set 2 number in url (http://localhost/projectname/campaigns/2)

Any idea how to do with codeigniter framework?

Pagination Code:

    // Pagination code for campaigns code start
    $config['total_rows'] = $this->Insta_campaigns_list_model->TotalCampaigns();

    // Check status value is number
    $status = $this->uri->segment(3);
    if(!ctype_digit($status)){
        $status = "1";
    }

    $config['base_url'] = base_url()."instagrammer/campaigns/".$status;
    $config['per_page'] = 3;
    $config['uri_segment'] = '4';

    $config['full_tag_open'] = '<div class=""><ul class="pagination pull-right">';

    $config['prev_tag_close'] = '</li>';

    $config['cur_tag_open'] = '<li class="active"><a href="">';
    $config['cur_tag_close'] = '</a></li>';

    $config['num_tag_open'] = '<li class="page">';
