- Open your text editor and create a new document named model.php model.php will contain functions that will connect to a database potentially return PDO statementobjects to the controller for processing. updateMessagesfunction updateMessages($id)This method will take a single parameter of id which is the saved id from the last or latest message displayed. It will conditionally select from the table “messages”, id, name, message, and time. The condition is that the field id is greater than the parameter for id. The return is the PDOStatement object with the row data from the query.5. calculate_new_balance Given a starting balance (a number), and a list of transaction tuples, calculate the final balance for an account. Transaction tuples are of the shape ("description", amount, "withdrawal") , or ("description", amount, "deposit"). The last entry in the tuple will be either "withdrawal" or "deposit". Every withdrawal decreases the balance of the account by the specified amount, and every deposit increases the balance. The return value is the new account balance, as a number. (which could be negative) Sample calls should look like: >>> calculate_new_balance(100, [("payday", 20, "deposit"), ("new shoes", 50, "withdrawal"), ("illicit winnings", 200, "deposit")]) 270 >>> calculate_new_balance (100, []) 100Do the needs to code.
