注销销毁CodeIgniter

Question

为什么我在注销时不能销毁会话？

我的身份验证控制器

public function index(){
$this->data['page_title'] = "User Login";
$this->load->view('templates/master', $this->data);
}
public function login(){
$username = $_POST['username'];
$password = $_POST['password'];
$data = $this->User_model->login ($username, $password);
if($data){  
$this->session->set_userdata('users', $data);
$session_data = array(
'username' => $username);
$this->session->set_userdata($session_data);
redirect('users');

}
else{
$this->session->set_flashdata
('loginfail','<div class="alert alert-danger"><a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
<strong>Danger !</strong> Invalid Email or Password .</div>');
return redirect("auth");

} 
}
public function logout()
{
$this->session->unset_userdata(array('username','id')); 
$this->session->sess_destroy(); 
echo '<pre>'; print_r($this->session->all_userdata()); 
exit; return redirect("auth");
}

我的PHP:

<a href="<?= base_url('auth/logout')?>" data-toggle="modal" data-target="#logoutModal">
<i class="fas fa-sign-out-alt fa-sm fa-fw mr-2 text-gray-400"></i>
Logout
</a>

试试这个

<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Auth extends MY_Controller {
public function index(){
/* You Should check Session before loading page */
if(empty($this->session->userdata('id'))){
redirect('users');
}    
$this->data['page_title'] = "User Login";
$this->load->view('templates/master', $this->data);
}
public function login(){
$username = $_POST['username'];
$password = $_POST['password'];
$data = $this->User_model->login ($username, $password);
if($data){  
$this->session->set_userdata('users', $data);
$session_data = array(
'username' => $username);
$this->session->set_userdata($session_data);
redirect('users');

}
else{
$this->session->set_flashdata
('loginfail','<div class="alert alert-danger"><a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
<strong>Danger !</strong> Invalid Email or Password .</div>');
return redirect("auth");

} 
}
public function logout()
{
$this->session->unset_userdata(array('username','id'));
$this->session->sess_destroy();
redirect("users");
}
}
