The following needs to be on a basic web page using the PHP request-response model to create a log-in form that permits the user to request access to an administration console for a Web-based product catalog of your choosing. Server-side scripting will authenticate the user based on valid users found in a text file verified by the server.

Once a user logs on to the administration console, he or she will need a form that will allow an authenticated user to add, edit, and delete products, product categories, and suppliers from the Web-based product catalog.
