Rbac

IMPORTANT!!

The only purpose of this package is to provide a version of zfr/rbac 1.2 that support PHP 8 and fixes the deprecation notices.

Rbac (not to be confused with ZfcRbac/LmcRbac) is a pure PHP implementation of the RBAC (Role based access control) concept. Actually, it is a Zend Framework 3 prototype of the ZF2 Zend\Permissions\Rbac component.

It aims to fix some design mistakes that were made to make it more usable and more efficient.

It differs on those points:

• A PermissionInterface has been introduced.
• RoleInterface no longer have setParent and getParent methods, and cannot have children anymore (this is used to implement a simpler "flat RBAC").
• A new HierarchicalRoleInterface has been introduced to allow roles to have children.
• Method hasPermission on a role no longer recursively iterate the children role, but only check its own permissions. To properly check if a role is granted, you should use the isGranted method of the Rbac class.
• Rbac class is no longer a container. Instead, it just has a isGranted method. The container was complex to properly handle because of role duplication, which could lead to security problems if not used correctly.

This library is used in LM-Commons/LmcRbacMvc v3.
