This is a very simple warehouse manager, where ADMINs can create suppliers and MANAGERs can create products. I made this to demonstrate how you can build a CRUD application with PHP using role-based authentication.
Just clone / download this repository, navigate into the project folder and run:
php -S localhost:4444
Now open http://localhost:4444
in a browser.
If you find any bug, kindly send a PR. Also you can open issues if you want to discuss something about this project.
