PHP bindings for 0MQ. The documentation is available here

This is a hardfork of the PHP Extension, updated for a PHP's newer extension sensibilities and API functions. As such, support for versions of PHP older than 8.1 and versions of libzmq below version 4 have been dropped.

Additionally the support for libczmq has been dropped as it wasn't documented and wasn't used at $work. Will be added back at a later date should it be required.

• libzmq 4.0.0 and above
• PHP 8.1 and above

$queue = new ZMQSocket(new ZMQContext(), ZMQ::SOCKET_REQ, "MySock1");

/* Connect to an endpoint */
$queue->connect("tcp://127.0.0.1:5555");

/* send and receive */
var_dump($queue->send("hello there, using socket 1")->recv());

?>
