Help me out on RBAC implemetations

My table structure is like PFA

how do I implement this RBAC…any possibilities to access this permissions table from all my controller?Any help would be much grateful Thanks!

I already read about this https://github.com/yiisoft/yii2/blob/master/docs/guide/security-authorization.md

but I dont want that schema model.So how can I use my schema model to implement this out?
