php - 如何回显 session 数据以查看配置文件

Question

如何使用 codeigniter 回显 session 数据以查看个人资料或帮助我通过 session 传递 id 来获取用户个人资料

Controller

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class User extends CI_Controller 
{    
    function __construct()
    {
        // Call the Model constructor
        parent::__construct();
        $this->load->database();
        $this->load->library('session');
        $this->load->helper('form');
        $this->load->library('form_validation');
        $this->load->model('User_Model');
        $this->load->helper('url');
        $this->load->library('parser');
    }

    public function index()
    {
        $this->load->view('login');
    }
    public function register()
    {
        $this->load->view('Register');
    }
    public function Save()
    {           
        $this->form_validation->set_rules('email', 'email', 'required');
        if ($this->form_validation->run() == false)
        {
            echo 'Please enter correct email.';
            exit;
        }

        $this->form_validation->set_rules('password', 'password', 'required');
        if ($this->form_validation->run() == false)
        {               
            echo 'Please enter password.';
            exit;
        }

        if ($this->form_validation->run() == true)
        {               
            $email = $this->input->post('email');
            $password = md5(trim($this->input->post('password')));
            $res = $this->User_Model->Save($email,$password);
            exit;
        }
    }
    public function Login()
    {
        $this->form_validation->set_rules('email', 'email', 'required');
        if ($this->form_validation->run() == false)
        {
            echo 'Please enter correct email.';
            exit;
        }

        $this->form_validation->set_rules('password', 'password', 'required');
        if ($this->form_validation->run() == false)
        {               
            echo 'Please enter password.';
            exit;
        }

        if ($this->form_validation->run() == true)
        {               
            $email = $this->input->post('email');
            $password = md5(trim($this->input->post('password')));
            $res = $this->User_Model->login($email,$password);
            echo $res; 
            exit;
        }
    }
    public function dashboard()
    {
        $this->load->view('welcome');
    }

    public function logout()
    {
        $this->session->sess_destroy();
        redirect(base_url().'index.php/User/'); 
    }
}   
?>

1. 使用原始 php，您可以使用 $_SESSION 检查 session 数据

2. 在 codeigniter 中，您可以使用 print_r($this->session->all_userdata()); 检查 session 数据
