"PHP" Refinement of the telegram bot

Good afternoon. There is a bot that makes payments through Yandex.Cassa and after payment invites the user to the paid channel and controls the following payments. In the case of non-payment - kicks the user out of the channel. And there is a small variation of the admin.

It is necessary to make improvements on the bot:

Make statistics on the bot. How much is paid per day, how much is paid, how much. This stats should be by day, as well as there should be a summary report (for all time) to make so that you can choose dates. Lets say not for the whole period, but from December 5 to December 7.
