(PECL stomp >= 0.1.0)
Stomp::begin -- stomp_begin — Starts a transaction
面向对象风格 (method):
$transaction_id
   [, array $headers
   ] ) : bool过程化风格:
$link
   , string $transaction_id
   [, array $headers
  ] ) : boolStarts a transaction.
link仅对过程化样式:由 stomp_connect() 返回的 stomp 连接标识符。
transaction_idThe transaction id.
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_commit() or stomp_abort().
