Logging Exceptions

Structured exception logging includes the message, file, line, trace, and any contextual data. Use a PSR-3 compatible logger like Monolog.

Example

<?php
use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$logger = new Logger("app");
$logger->pushHandler(new StreamHandler("logs/app.log", Logger::ERROR));

try {
    $result = riskyOperation($input);
} catch (Exception $e) {
    $logger->error("Operation failed", [
        "exception" => $e->getMessage(),
        "file"      => $e->getFile(),
        "line"      => $e->getLine(),
        "trace"     => $e->getTraceAsString(),
        "input"     => $input,  // contextual data
    ]);

    // Return graceful error to user
    return response()->json(["error" => "Operation failed"], 500);
}

Pro Tip

Log the full exception context (message, trace, input data) but show only a generic message to end users.
