PHP/SQL

Consider the banking example below:

branch (branch-name, branch-city, assets) customer (customer-name, customer-street, customer-city) account (account-number, branch-name, balance) loan (loan-number, branch-name, amount) depositor (customer-name, account-number) borrower (customer-name, loan-number)

Write PHP code for the following problems:

1. Create a php file to display the names and cities of customers who have a loan at Perryridge branch from the web.

2. Create the corresponding html and php files so that a user can insert the following customer into the database from a web browser. After the insertion, display all the customers from the web.
