Answer 1

1. The $result_set is outside the function scope. You can't access it within the function.
2. You're selecting from a string not a table name

Try the following changes:

set_charset("utf-8"); //Better to do it this way
    $result_set = $mysqli->query ("SELECT * FROM `product`"); //Not the ` instead of '

    while (($row = $result_set->fetch_assoc()) != false) {
        print_r ($row);
        echo "
";
    }
    $mysqli -> close();
}

You can run this function from anywhere.
