PHP 访问控制的实施方案

use RoleBasedControl as RBC;

$user = new User();
$user->setUsername('admin');

$role = new Role();
$role->setName('manager');

$permission = new Permission();
$permission->setPermission('manage_users');

$rbac = new RBC();
$rbac->assignUserToRole($user, $role);
$rbac->assignPermissionToRole($permission, $role);

if ($rbac->hasAccess($user, $permission)) {
  // 允许访问
} else {
  // 拒绝访问
}

use AttributeBasedControl as ABC;

$user = new User();
$user->setAttribute('age', 25);
$user->setAttribute('location', 'USA');

$resource = new Resource();
$resource->setAttribute('sensitivity', 'high');

$policy = new Policy();
$policy->setAttribute('age', '>= 21');
$policy->setAttribute('location', 'USA');
$policy->setPermission('read');

$abc = new ABC();
$abc->addPolicy($policy);

if ($abc->hasAccess($user, $resource)) {
  // 允许访问
} else {
  // 拒绝访问
}

$user = $_SESSION['user'];

if ($user->hasRole('admin')) {
  // 显示管理仪表板
} else {
  // 重定向到主页
}
