// Get the customer record from the database $customer = get_customer_by_id($customer_id); // Overwrite the address field with the new value $customer['address'] = $_POST['new_address']; // Save the updated record back to the database update_customer($customer);This code snippet assumes that you have already defined functions for retrieving and updating customer records in your application. The package library for the overwriteForm model in PHP is not specified in this question. However, it is likely that this is part of a larger framework or library designed for building web applications in PHP. Some examples of popular PHP frameworks include Laravel, Symfony, and CodeIgniter.
