Php 角色类模型的正确实现

我一直在尝试将一个角色类模型模式实现到用PHP编写的网站用户访问机制中。不过我有一些疑问。以下是相关代码的简化版本：

class User 
{
        public $role;
        public $uid;        
        public function setRole($role)
        {
            $this->role = $role;
        }
} 
// role classes responsible for restricted actions
class BaseRole {} 
class AdminRole extends BaseRole
{ 
       // do something adminish + log action into database (with User ID)
       public function SomethingAdminish($admin_id) { }
}
$user = new User();
$user->setRole(new AdminRole());

// pass Admin ID (User ID) into method
$user->rola->SomethingAdminish($user->uid);

我在这里看到了一些弱点：

将任何其他$user->uid传递到SomethingAdminish方法将 将不正确的信息登录到我的日志系统错误的用户ID 如果我决定用上述方法记录其他用户信息， 本质上，我必须将整个用户对象作为参数传递， 像这样：

$user->rola->SomethingAdminish$user

我可能错过了一些重要的东西。你们能解释一下这个问题吗

我个人会设置并使用访问控制列表ACL模式

资源是控制访问的对象

角色是可以请求访问资源的对象

简单地说，角色请求访问资源。例如，如果 停车场服务员请求进入一辆车，然后停车场服务员 是请求角色，汽车是资源，因为访问 这辆车可能不是每个人都有

下面是一个使用上述代码的基本示例，说明ACL流的外观

// Create an ACL object to store roles and resources. The ACL also grants
// and denys access to resources.
$acl = new Acl();

// Create 2 roles. 
$adminRole = new Acl_Role('admin');
$editorRole = new Acl_Role('editor');

// Add the Roles to the ACL.
$acl->addRole($adminRole)
    ->addRole($editorRole);

// Create an example Resource. A somethingAdminish() function in this case.
$exampleResource = new Acl_Resource('somethingAdminish');

// Add the Resource to the ACL.
$acl->add($exampleResource);

// Define the rules. admins can are allowed access to the somethingAdminish
// resource, editors are denied access to the somethingAdminish resource.
$acl->allow('admin', 'somethingAdminish');
$acl->deny('editor', 'somethingAdminish');

下面是用户对象如何与ACL交互

// Load the User
$userID = 7;
$user = User::load($userID);

// Set the User's Role. admin in this case.
$user->setRole($adminRole);

// Query the ACL to see if this User can access the somethingAdminish resource.
if ($acl->isAllowed($user, 'somethingAdminish')){

    // Call the somethingAdminish function. Eg:
    somethingAdminish();

    // Log the action and pass the User object in so you can take any information
    // you require from the User data.
    $acl->logAction('somethingAdminish', $user)

}else{
    die('You dont have permission to perform the somethingAdminish action.')
}
