Telegram API, get the sender's phone number?
<p>I realize it is not possible to use <code>a Bot</code> to receive a sender's phone number.<br>
I do, however, need to implement a bot-like client, that responds to anyone who is messaging it. I am using PHP on apache.</p>

<p>It is not a Bot, as it does not take commands, but rather responds to sent text from anyone who has that phone number. So you add the user as a contact (using a phone number), and then send text to it.</p>

<p>My goal is to realise the sender's phone number as I receive it, I saw on the <a href="https://core.telegram.org/methods#registration-authorization" rel="noreferrer">Telegram API</a> that there's a peer ID, but I can't find how to get the phone number if that's even possible... </p>
