ZMQContext::getSocketCreate a new socket


public ZMQContext::getSocket(int $type, string $persistent_id = null, callable $on_new_socket = null): ZMQSocket

Shortcut for creating new sockets from the context. If the context is not persistent the persistent_id parameter is ignored and the socket falls back to being non-persistent. The on_new_socket is called only when a new underlying socket structure is created.
