Production Error Management Strategies
In a production environment, managing errors effectively requires more than just recording them. You need to combine several strategies to ensure your application remains stable, secure, and maintainable. The best practices for production error management include:
- Logging all errors to a secure, persistent location;
- Using real-time monitoring tools to track error trends and system health;
- Setting up alerting systems to notify responsible parties immediately when critical issues occur.
By integrating logging, monitoring, and alerting, you can quickly detect, diagnose, and resolve issues before they impact users. This approach also helps you spot recurring problems, analyze root causes, and meet compliance or auditing requirements. The ultimate goal is to minimize downtime and data loss, while protecting sensitive information from being exposed.

'/alerts.log', date('c') . " ALERT: $message\n", FILE_APPEND); } // Custom error handler function productionErrorHandler($errno, $errstr, $errfile, $errline) { $errorMsg = "[$errno] $errstr in $errfile on line $errline"; // Log error to file error_log(date('c') . " ERROR: $errorMsg\n", 3, __DIR__ . '/errors.log'); // Send alert for critical errors if ($errno === E_ERROR || $errno === E_USER_ERROR) { sendAlert($errorMsg); } // Don't display error details to the user in production return true; } // Set the custom error handler set_error_handler('productionErrorHandler'); // Example: trigger an error trigger_error("Database connection failed!", E_USER_ERROR); // Example: trigger a warning (logged but not alerted) trigger_error("Deprecated function used.", E_USER_WARNING); echo "Application continues running safely.\n";
The code above demonstrates a robust error management workflow suitable for production environments. When an error occurs, the custom error handler logs detailed information to a secure file, ensuring a persistent record for later analysis. For critical errors, such as those that might cause application failure, the handler also triggers an alert using the sendAlert function—this could be adapted to send emails, SMS, or integrate with third-party monitoring systems. By separating error logging from alerting, you ensure that routine issues are tracked without overwhelming your team, while urgent problems receive immediate attention. Importantly, error details are not displayed to users, preserving security and user experience.
