Ok So after taking your advice to use the PUB/SUB, here´s a revised version of
my code. It doesn´t give me an error now but the page just keeps loading
endlessly without any message displayed.
$context = new ZMQContext();
echo "Collecting data from the MDT server\n";
$subscriber = new ZMQSocket($context, ZMQ::SOCKET_SUB);
$subscriber->connect("tcp://24.187.208.22:2060");
$subscriber->setSockOpt(ZMQ::SOCKOPT_SUBSCRIBE);
//while(true){
$string = $subscriber->recv();
echo $string;
//}
Does it matter that i´m running this on my localhost?

It depends on what he wants to do, if he wants to have several sockets receiving
the same message, he then should use PUB/SUB, otherwise PUSH/PULL pattern should
work smoothly.
PUB/SUB should work in a setup that looks like this ...
[Publisher]
-
-
------> [Subscriber]
-
------> [Subscriber]
-
------> [Subscriber]
In that setup *all* the subscribers receive the *same* message the publisher
sends. Think RSS.
PUSH/PULL should work in a setup more similar to this ...
[Pusher]
.
.
......> [Puller]
......> [Puller]
......> [Puller]
Where only *one* of the pullers will receive the message and other's won't, this
works best if you want an LRU functionality (think load-balancer).
