Question

我已经看过并检查过其他stackoverflow问题，这个问题的常见答案是

确保<?php代码
之前没有空格

即使在浏览了有关此问题的其他博客和文章后，我仍然面临同样的错误。但是如果我删除会话的负载，一切正常。

我的错误：

A PHP Error was encountered

Severity: Warning

我的控制员：

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

class Home extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
        $this->load->library('session');
        $this->load->helper('url');
        $this->load->helper('cookie');
    } 

    public function index()
    {
        $this->load->view('header');
        $this->load->view('welcome_message');
        $this->load->view('footer');
    }
}

?>

Answer 1

会话库正在尝试写入磁盘，这也恰好涉及mkdir（）。您需要使该路径可写或将会话数据目录更改为已经可写的其他内容。

在配置中检查“sess_save_path”。有关会话配置的更多文档： https://www.codeigniter.com/user_guide/libraries/sessions.html#session-preferences

Answer 2

更改（Codeigniter 3.0.4上的config / config.php第374行）

$config['sess_save_path'] = 'NULL';

到

$config['sess_save_path'] = BASEPATH.'ci_sessions';

https://www.codeigniter.com/user_guide/libraries/sessions.html

请注意

如果您已从先前版本的CodeIgniter和您升级如果没有配置“ sess_save_path ”，则会话库将会查找旧的“ sess_table_name ”设置并改为使用它。请不要依赖这种行为，因为它将来会被删除。

在我的codeigniter 3.0.4控制器中加载会话库后立即面临错误
