ZMQContext::getSocket
(PECL zmq >= 0.5.0)
ZMQContext::getSocket — Create a new socket
Description
$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
-
type -
ZMQ::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.
Return Values
Returns a ZMQSocket object.
Errors/Exceptions
Throws ZMQSocketException on error.
