Save state in telegram bot?

Question

PHP

Hello guys, I use this library https://github.com/irazasyed/telegram-bot-sdk

And now the question arose, how to make state saving in it?
That is, I make a bot for a survey or an application, and so on. Where step by step you need to specify the full name and phone number (example).

Answer 1

Connect the database and that's it

Answer 2

Either a DB or use Python and store form[chat_id] values

Answer 3

If the library is unprincipled, then I recommend finding a library where the state machine is already implemented. For example aiogram or pyTelegramBotApi. (aiogram is better)
