Example #1 Stile orientato agli oggetti
<?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);
?>
Il precedente esempio visualizzerĂ qualcosa simile a:
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 Stile procedurale
<?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);
?>
Il precedente esempio visualizzerĂ qualcosa simile a:
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" } }
