Are there examples of a bot so that the bot responds to requests?

Question

Bots

Created a bot in telegram and got a token and chat id.
I send messages to chat in php. This works especially interesting for site event notifications via get requests. Everything is great.
But in my implementation it is one-way communication.
I would like to learn how to do such a thing: The user writes a phone number or order number to the bot, somehow all this is processed and in response to the user a message about the status of the order is received.
How can this be done, preferably in php? Are there simple examples?

Answer 1

You need to install a database, for example mysql. It stores records of orders: number, status and everything else. When the user writes a message with the order number, it is necessary to execute a query to the database "SELECT status FROM table_name_with_orders WHERE order_number=entered_number_by the user;" send the result of the request to the user.
To respond to incoming messages, you need to set up a webhook
