In PHP payment processing, how do I log effectively?

Logging is an essential aspect of processing payments with PHP. Effective logging can help you track the status of transactions, diagnose issues, and maintain a clear audit trail. Here’s how to implement logging effectively in your payment processing script.

<?php // Define log file $logFile = 'payment_log.txt'; // Function to log messages function logMessage($message) { global $logFile; // Use global variable $timestamp = date("Y-m-d H:i:s"); $formattedMessage = "[$timestamp] $message" . PHP_EOL; file_put_contents($logFile, $formattedMessage, FILE_APPEND); } // Example payment processing try { // Simulate payment processing $paymentStatus = 'success'; // or 'failure' logMessage("Payment processing started."); if ($paymentStatus === 'success') { logMessage("Payment processed successfully."); } else { throw new Exception("Payment failed."); } } catch (Exception $e) { logMessage("Error: " . $e->getMessage()); } ?>
