In PHP e-commerce, how do I gracefully handle failures?

In an e-commerce application, gracefully handling failures is critical for maintaining a good user experience. This involves providing clear feedback to users when errors occur and ensuring that the application can recover or guide users appropriately.

Example Code for Error Handling in PHP

<?php function processOrder($orderData) { try { // Code to process the order if (!$orderData['payment_successful']) { throw new Exception('Payment failed.'); } // Additional processing... echo "Order processed successfully!"; } catch (Exception $e) { // Log the error error_log($e->getMessage()); // Provide user-friendly error message echo "Something went wrong while processing your order. Please try again."; } } // Example usage $orderData = ['payment_successful' => false]; // Simulating a payment failure processOrder($orderData); ?>
