I have a PHP daemon that listens to UDP and ZMQ traffic in a non-blocking way - I use stream_select() on both the UDP listening socket and the ZMQ socket (the ZMQ extension happily provides the underlying socket FD so we can just add it to the select() arrays).

My daemon also runs jobs once every second, so using stream_select() with a timeout is very flexible, I can process ZMQ and UDP as soon as someething is there to read without waiting for the timeout to expire, yet run jobs every second without a problem.

I understand that there used to be a ->getSocket() method on the $connection in the AMQP lib, but it's apparently gone.

How can I add the AMQP lib's socket to the select() pool so I can gracefully listen to UDP, ZMQ, AMQP and maintain the flexibility of stream_select() ?

I understand that there are mechanisms in the AMQP lib to do that just with the AMQP sockets, but I also need to react swiftly to my other connections such as UDP and ZMQ.

Thanks!
