function redeem()
{
    $this->db->select('questionEng');
    $this->db->from('question');
    $results  =  $this->db->get()->result_array();
    foreach($results as $result)
    {
        echo "<pre>";
        print_r($result);
        echo "<pre>";
    }
    die;
    $this->load->view('admin/redeem');
}

Answer 2

In your code you have used die in for loop. So you script will stop working after first looping. So you script printing only one record.

function redeem()
{
    $this->db->select('questionEng');
    $this->db->from('question');
    $query=$this->db->get();
    foreach($query->result_array() as $result)
    {
        print_r($result);
    }
    die;
    $this->load->view('admin/redeem');
}

Answer 3

remove die; at all, also why you print result you should pass it to your view then read in view:

function redeem()
{
    $this->db->select('questionEng');
    $this->db->from('question');
    $query=$this->db->get();
    $arr_data = $query->result_array() ;
    $this->load->view('admin/redeem', $arr_data);
}

Answer 4

    public function REDEEM()
    $this->db->select('questionEng' );  
    $this->db->from('question');
    $this->db->where(select any colum you want);
    $query=$this->db->get();
    $list=$query->result();
    return $list;

Then load the model in controller as $res = $this->your model name->REDEEM(); echo json_encode($res);exit; or load view in place of json

Answer 5

You can do this.

function redeem()
{
    $this->db->select('*');
    $this->db->from('question');
    $query=$this->db->get();
    $results  =  $query->result_array();

        echo "<pre>";
        print_r($results); // to print results
        echo "<pre>"; 


    $this->load->view('admin/redeem',$results); //pass to view
}
