(PECL zmq >= 0.5.0)
ZMQContext::getSocket — Create a new socket
Description
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.
Parameters
typeZMQ::SOCKET_*constant to specify socket type.persistent_id- If
persistent_idis 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.
