В следующем примере я создаю файл с данными из формы html, сгенерированный файл в текстовом формате. Я хочу жестко закодировать комментарий в загруженном файле, просто для информационных целей. Возможно ли это сделать? Любая помощь будет принята с благодарностью. Например, в загруженном файле
я хочу добавить комментарий вверху перед 'PDU' как '# Начальная конфигурация детализации'
Спасибо
