我想破坏会话数据但不能这样做。

当我点击退出按钮时，它总是显示出现了一些问题，var_dump（）的值显示为NULL。

显示消息，例如消息： session_destroy（）：尝试销毁未初始化的会话

控制器： Users.php

class Users extends CI_Controller
{

    public function logout()
    {
        $result = $this->session->sess_destroy();
        var_dump($result = $this->session->sess_destroy());
        if($result)
        {
            echo "You are logged Out!!";
        }
        else
        {
            echo "Some problem has been occured";
        }
    }

public function login()
    {
        $this->form_validation->set_rules('customer-id', 'custid', 'trim|required');
        if ($this->form_validation->run() == FALSE) 
        {
            echo "Please Enter Customer ID";
        }
        else
        {


            $this->form_validation->set_rules('pass', 'password', 'trim|required');
            if ($this->form_validation->run() == FALSE) 
            {
                echo "Please Enter Password";
            }
            else
            {
                $custid = $this->input->post("customer-id");
                $password = $this->__encrip_password($this->input->post('pass'));

                if('loginuser' == TRUE)
                {


                    $data = $this->user_model->get_username($custid);
                    //$data['custid'] = $custid;
                    $this->session->set_flashdata('data',$data);
                    $this->session->keep_flashdata('data');
                    var_dump($this->session->flashdata('data'));
                    //echo $data;
                    redirect('users/clientview');
                    //$this->load->view('clientview', $data);

                }
                else
                {
                    $result = $this->user_model->login($custid, $password);
                    if ($result) 
                    {

                        $sessiondata = array('customer-id' => $custid, 
                                'loginuser' => TRUE);

                        $this->session->set_userdata($sessiondata);
                        $data['custid'] = $custid;
                        echo "You have successfully logged-in :)";

                    }
                    else
                    {
                        echo $custid;
                        echo $password;
                        echo "Invalid Username or Password";
                    }
                }   
            }
        }
    }
}

您正试图破坏会话TWICE。

$result = $this->session->sess_destroy();
var_dump($result = $this->session->sess_destroy());

执行此操作，因为第一行会破坏会话，第二行会抛出有关未初始化会话的错误，因为您尝试在第二行中再次销毁它。

$result = $this->session->sess_destroy();
var_dump($result);

我也不确定sess_destroy()是否实际上会返回任何内容供您测试？

无法破坏会话
