PHP MySQL Zend-ACL - graphically display ACLs:

I have one MySQL DB table as below resource table :

+----+-----------+------------+
| id | name      | type       |
+----+-----------+------------+
| 1  | guest     | user       |
| 2  | member    | user       |
| 3  | moderator | user       |
| 4  | owner     | user       |
| 5  | admin     | user       |
| 6  | index     | controller |
+----+-----------+------------+

The following table is a table of rules :

+----+---------+------+-------------+----------------------+
| id | user_id | rule | resource_id | extras               |
+----+---------+------+-------------+----------------------+
| 1  | 2       | 3    | 1           | null                 |
| 2  | 3       | 3    | 2           | null                 |
| 3  | 4       | 3    | 3           | null                 |
| 4  | 5       | 3    | 4           | null                 |
| 5  | 6       | 1    | 1           | index,login,register |
| 6  | 6       | 2    | 2           | login,register       |
| 7  | 6       | 1    | 2           | logout               |
+----+---------+------+-------------+----------------------+

OK, sorry for the length, but I'm trying to give a complete picture of what I'm trying to do. Thus, how it works, the role (as a user) can be given (typically: 1) access to the controller, the role can inherit (Rule 3), another role or role and rejected (rule 2) access to the controller. (A user is a resource, and a controller is a resource)

Access to actions is granted / denied using the additional parameters column.
