    $this->load->view('details_view', $data);
}

the function of my model

function getdata () {
        $this->db->select ('subject, id, problem'); // field name
        $sql = $this->db->get('info'); // table name
        if ($sql->num_rows () >0) {

Try this:

<?php echo $info[0]->problem;  ?>

In getdata_by_id, you are returning $sql->result(). This gives an array of objects. You can use $sql->row() to return you an object of just that row.
