推荐答案

一个新的配置文件。

$config['controllers'] = array(
    'blog',
    'events',
    'news', // etc.
);

否则，您将扫描会占用资源的目录。但你可以这样做：

Otherwise, you will be scanning directories which will eat up resources. But you could do it like this:

    $controllers = array();
    $this->load->helper('file');

    // Scan files in the /application/controllers directory
    // Set the second param to TRUE or remove it if you 
    // don't have controllers in sub directories
    $files = get_dir_file_info(APPPATH.'controllers', FALSE);

    // Loop through file names removing .php extension
    foreach (array_keys($files) as $file)
    {
        $controllers[] = str_replace(EXT, '', $file);
    }
    print_r($controllers); // Array with all our controllers

由于文件名匹配控制器名称，现在你应该有一个数组所有的控制器。这不是完美的虽然有几个原因，但应该适用于大多数设置。

Since file names match controller names, now you should have an array of all your controllers. This isn't perfect though for several reasons, but should work for most setups.

我个人使用高度修改的目录结构，所以这不会为我工作，和一些控制器，我也想忽略。另一个选择是将结果缓存到文件，但这是一个单独的教程。

Personally I use a highly modified directory structure, so this wouldn't work for me, and some controllers I would want to ignore as well. Another option would be to cache the results to a file, but that's a separate tutorial.

我强烈建议在配置文件中定义它们，这样你可以存储其他有用的与您的访问控制直接相关的信息，并避免递归扫描目录的巨大开销。

I highly suggest defining them in a config file, this way you can store other useful information directly related to your access control and avoid the huge overhead of recursively scanning directories.
