Take an example from the ZeroMQ documentation

<?php /* * Hello World server * Binds REP socket to tcp://*:5555 * Expects "Hello" from client, replies with "World" * @author Ian Barber <ian(dot)barber(at)gmail(dot)com> */ $context = new ZMQContext(1); // Socket to talk to clients $responder = new ZMQSocket($context, ZMQ::SOCKET_REP); $responder->bind("tcp://*:5555"); while (true) { // Wait for next request from client $request = $responder->recv(); printf ("Received request: [%s]\n", $request); // Do some 'work' sleep (1); // Send reply back to client $responder->send("World"); }

In this case, the execution of the code will stop on line

 $request = $responder->recv();

Question: how to use ZeroMQ in PHP without context switching? (if there is no request, then just ignore the code associated with ZeroMQ)
