Stomp::send

stomp_send

(PECL stomp >= 0.1.0)

Stomp::send -- stomp_sendSends a message

Description

Object oriented style (method):

public bool Stomp::send ( string $destination , mixed $msg [, array $headers ] )

Procedural style:

bool stomp_send ( resource $link , string $destination , mixed $msg [, array $headers ] )

Sends a message to the Message Broker.

Parameters

link

Procedural style only: The stomp link identifier returned by stomp_connect().

destination

Where to send the message

msg

Message to send.

headers

Associative array containing the additional headers (example: receipt).

Return Values

Returns TRUE on success or FALSE on failure.

Notes

Note:

A transaction header may be specified, indicating that the message acknowledgment should be part of the named transaction.

Tip

Stomp is inherently asynchronous. Synchronous communication can be implemented adding a receipt header. This will cause methods to not return anything until the server has acknowledged receipt of the message or until read timeout was reached.

Examples

See stomp_ack().

Without a receipt header your application will fire messages potentially faster than the broker can receive them at. The broker may issue failure notices however STOMP being asynchronous your client won't get to see it.

Without a receipt ActiveMQ (5.5.0) with ProducerFlowControl turned on drops messages (even persistent ones) and my application knows nothing about it (send() returned true). With receipt header specified the STOMP library handles the wait for the receipt acknowledgement for you - you are essentially automatically throttled.
