如何在 PHP 函数中使用日志记录上下文？

// 添加一个键值对$logger->withContext('user_id', $userId)->info('User logged in');// 添加一个关联数组$logger->withContext(['user_id' => $userId, 'username' => $username])->info('User logged in');

function processOrder($orderId) {    try {        // 尝试处理订单        // 如果成功，记录成功消息及其上下文        $logger->withContext(['order_id' => $orderId])->info('Order processed successfully');    } catch (Exception $e) {        // 如果失败，记录错误消息及其上下文        $logger->withContext(['order_id' => $orderId, 'exception' => $e])->error('Order processing failed');    }}
