Расскажите про сериализатор Symfony

В Symfony, сериализатор — это сервис, который преобразует данные между различными форматами, такими как JSON, XML, YAML или CSV, и PHP-объектами. Компонент сериализации в Symfony — это мощный инструмент, используемый для преобразования объектов в сериализуемый формат и обратно. Он особенно полезен для API, где обмен данными часто требует преобразования в структурированные текстовые форматы и обратно.

Telegram auto-delete message, expiring invites, and more

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
