我以前使用 cakephp，现在使用 codeigniter，但不幸的是没有任何身份验证或 ACL 内置库..经过更多搜索，我找到了一个很好的库，但我不知道如何使用它..它不是使用示例它..任何人都创建了控制器和模型作为示例...感谢您的帮助
<?php
(defined('BASEPATH')) OR exit('No direct script access allowed');
class acl {
/* Actions::::
* Create 1
* Read 2
* Update 4
* Delete 8
* The allowance is made by a sum of the actions allowed.
* Ex.: user can read and update (2+4)=6 … so ill put 6 instead of 1 or 0.
*
* if(!$this->acl->hasPermission(‘entries_complete_access')) {
echo “No no”;
} else
* echo “yeah”;
}
