Interview question

How should exceptions be handled differently in development vs production? Development बनाम production में exceptions को अलग तरीके से कैसे handle करें?

Answer

Aspect	Development	Production
Error display	Show full stack trace to developer	Never show stack traces or internal messages to users
Logging	Optional, console is often enough	Mandatory - log to file, or a service like Sentry/CloudWatch
User-facing message	Technical detail is fine	Generic, friendly message plus a reference/error ID
HTTP status code	Less critical	Must return the correct status (500, 422, 404, etc.)

try {
    chargeCard($order);
} catch (Throwable $e) {
    Log::error($e->getMessage(), ['trace' => $e->getTraceAsString()]);

    if (app()->environment('production')) {
        return response()->json(['message' => 'Payment failed. Please try again.'], 500);
    }
    throw $e; // rethrow with full detail locally
}

Interview tip: This question tests security awareness as much as PHP knowledge - always mention that leaking stack traces in production can expose file paths, database structure, and even credentials.

पहलू	Development	Production
Error display	Developer को पूरा stack trace दिखाएं	Users को कभी stack traces या internal messages न दिखाएं
Logging	Optional, console अक्सर काफी है	ज़रूरी - file में log करें, या Sentry/CloudWatch जैसी service
User-facing message	Technical detail ठीक है	Generic, friendly message plus एक reference/error ID
HTTP status code	कम critical	सही status रिटर्न होना चाहिए (500, 422, 404, आदि)

try {
    chargeCard($order);
} catch (Throwable $e) {
    Log::error($e->getMessage(), ['trace' => $e->getTraceAsString()]);

    if (app()->environment('production')) {
        return response()->json(['message' => 'Payment failed. Please try again.'], 500);
    }
    throw $e; // locally पूरी डिटेल के साथ rethrow
}

इंटरव्यू टिप: यह सवाल PHP knowledge जितना ही security awareness टेस्ट करता है - हमेशा बताएं production में stack traces leak होने से file paths, database structure, और credentials तक expose हो सकते हैं।
