Stomp::unsubscribe -- stomp_unsubscribe — Removes an existing subscription
面向对象风格 (method):
$destination
[, array $headers
] )过程化风格:
$link
, string $destination
[, array $headers
] )Removes an existing subscription.
link仅对过程化样式：由 stomp_connect() 返回的 stomp 连接标识符。
destination
Subscription to remove.
headers关联数组包含附加的头信息（例如： receipt）。
成功时返回 TRUE， 或者在失败时返回 FALSE。
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.
See stomp_ack().
