ZMQContext::getSocket — Create a new socket
$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.
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.
Example #1 A ZMQContext() example
Basic usage
<?php
$context = new ZMQContext ();
$socket = $context -> getSocket ( ZMQ :: SOCKET_REQ , 'my sock' );
$socket -> connect ( "tcp://example.com:1234" );
$socket -> send ( "Hello there" );
$message = $socket -> recv ();
echo "Received message: { $message } \n" ;
?>
Returns a ZMQSocket object on success. Throws ZMQSocketException on error.
