ZMQContext::getSocket — Create a new socket

Description

public ZMQSocket ZMQContext::getSocket ( int $type [, string $persistent_id = NULL [, callback $on_new_socket = NULL ]] )

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.

Parameters

type: ZMQ::SOCKET_* constant to specify socket type.
persistent_id: If persistent_id is specified the socket will be persisted over multiple requests.
on_new_socket: Callback function, which is executed when a new socket structure is created. This function does not get invoked if the underlying persistent connection is re-used. The callback takes ZMQSocket and persistent_id as two arguments.
