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

范例

Example #1 面向对象风格

<?php/* connection */try {    $stomp = new Stomp('tcp://localhost:61613');} catch(StompException $e) {    die('Connection failed: ' . $e->getMessage());}/* subscribe to messages from the queue 'foo' */$stomp->subscribe('/queue/foo');/* read a frame */var_dump($stomp->readFrame());/* close connection */unset($stomp);?>

以上例程的输出类似于：

object(StompFrame)#2 (3) {
  ["command"]=>
  string(7) "MESSAGE"
  ["headers"]=>
  array(5) {
    ["message-id"]=>
    string(41) "ID:php.net-55293-1257226743606-4:2:-1:1:1"
    ["destination"]=>
    string(10) "/queue/foo"
    ["timestamp"]=>
    string(13) "1257226805828"
    ["expires"]=>
    string(1) "0"
    ["priority"]=>
    string(1) "0"
  }
  ["body"]=>
  string(3) "bar"
}

Example #2 过程化风格

<?php/* connection */$link = stomp_connect('ssl://localhost:61612');/* check connection */if (!$link) {    die('Connection failed: ' . stomp_connect_error());}/* subscribe to messages from the queue 'foo' */stomp_subscribe($link, '/queue/foo');/* read a frame */$frame = stomp_read_frame($link);/* close connection */stomp_close($link);?>

以上例程的输出类似于：

array(3) {
  ["command"]=>
  string(7) "MESSAGE"
  ["body"]=>
  string(3) "bar"
  ["headers"]=>
  array(6) {
    ["transaction"]=>
    string(2) "t1"
    ["message-id"]=>
    string(41) "ID:php.net-55293-1257226743606-4:3:-1:1:1"
    ["destination"]=>
    string(10) "/queue/foo"
    ["timestamp"]=>
    string(13) "1257227037059"
    ["expires"]=>
    string(1) "0"
    ["priority"]=>
    string(1) "0"
  }
}
