Php 扩展控制器代码点火器

我已经在IIS上安装了Codeigniter。一切都很顺利

我正在尝试扩展CI_控制器类。我这样做的原因是在构造函数中进行安全检查。某些控制器将扩展CI_控制器。一些需要安全的控制器将扩展MY_控制器。这对我来说似乎是个好办法

到目前为止，我遵循了以下说明：

但是当我调用扩展我的_控制器的页面时，我得到一个空白页面。 检查Firebug中的网络选项卡，我看到“500内部服务器错误” 我检查了我的CI日志，我看到：

现在，对于正常参考点，当我加载任何不扩展我的_控制器的控制器时，我看到：

谁能告诉我怎么了

我的控制器

class MY_Controller extends CI_Controller{

    private static $instance;

    /**
     * Constructor
     */
        function __construct()
        {
            parent::__construct();
        }

    public static function &get_instance()
    {
        return self::$instance;
    }
}

扩展它的控制器：

class Project extends MY_Controller{

    public function __construct()
        {
            parent::__construct();
            $this->load->database();        
            $this->load->model('user_model');
        }

    public function index()
    {
            var_dump("hi");
        }


}

将MY_控制器更改为：

<?php

class MY_Controller extends CI_Controller
{

    /**
     * Constructor
     */
    public function __construct()
    {
        parent::__construct();
    }

}

首先，在扩展控制器之前，一切都正常吗？第二，你能展示你的
MY_Controller
类的代码和扩展它的控制器吗。。。不是全部，只是顶部。最后，文件名是否与类名完全匹配（区分大小写）？好的，Ross，我添加了代码以回答您的问题：每个不扩展我的\u控制器的控制器都工作得很好。MY_Controller.php文件名与“MY_Controller”的控制器名完全匹配（包括大小写）。@GRY，为了排除一个问题，您有$config['subclass_prefix']='MY_'；在application/config/config.php（？）@eduardata Yes先生中定义。我已经在config中将子类前缀定义为“MY_u3;”，我刚刚测试了代码，它不会在
private static$instance中抛出错误或方法…但仍然不需要：）
