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"
}
