Writing MadelineProto async, I really enjoyed working with the AMPHP framework: it is very fast, has multiple packages to work asynchronously with HTTP requests, websockets, databases (MySQL, redis, postgres, DNS, sockets and much more)!

I chose AMPHP instead of the more famous ReactPHP due to its speed, rich set of libraries and extreme ease of use.

Working with its devs is also nice; I already contributed to the amphp's libraries with some improvements and bugfixes (I will soon also implement a DNS over HTTPS client for AMPHP, to implement in MadelineProto's artax), and I invite you to do the same!

Even if you don't contribute to AMPHP, you can still use it: as I mentioned above, there are MANY libraries to work asynchronously with files, databases, DNS, HTTP; there's even an async windows registry client, used by the DNS client to fetch default DNS servers on windows!

When you use MadelineProto async, you have to also use an amphp async database client, artax instead of curl and guzzle, and so on: otherwise, the speed of MadelineProto async may be reduced by blocking behaviour of your code.
