Assume that mam class is a black box
new user class does not have access to database
mam class has some methods that allow me to run instance queries in index.php
there is no customized method in mam class that loops using foreach (array or select table)
I can not run queries without a method from mam class
I do not want to edit mam class because whenever programmer makes edit: sends new class to me (which will not have my old edits)
Is there a way to create user class with instance of hardcoded usernames and passwords using object oriented code with no database connection.
