ibase_trans - Begin a transaction

SYNOPSIS
       resource ibase_trans ([int  $trans_args], [resource  $link_identifier])

DESCRIPTION
       resource ibase_trans ([resource	$link_identifier], [int  $trans_args])

	Begins a transaction.

       Note

	       The  first  call  to  ibase_trans(3)  will  not	return	the  default  transaction  of  a  connection.  All transactions started by
	      ibase_trans(3) will be rolled back at the end of the script if they were not committed or rolled back by either  ibase_commit(3)	or
	      ibase_rollback(3).

       Note

	       This function will accept multiple $trans_args and $link_identifier arguments. This allows transactions over multiple database con-
	      nections, which are committed using a 2-phase commit algorithm. This means you can rely on the updates to either	succeed  in  every
	      database, or fail in every database. It does NOT mean you can use tables from different databases in the same query!

	       If  you	use  transactions  over  multiple  databases,  you  will have to specify both the $link_id and $transaction_id in calls to
	      ibase_query(3) and ibase_prepare(3).

PARAMETERS
	      o $trans_args
		-$trans_args  can  be  a  combination  of  IBASE_READ,	 IBASE_WRITE,	IBASE_COMMITTED,   IBASE_CONSISTENCY,	IBASE_CONCURRENCY,
		IBASE_REC_VERSION, IBASE_REC_NO_VERSION, IBASE_WAIT and IBASE_NOWAIT.

	      o $link_identifier
		- An InterBase link identifier. If omitted, the last opened link is assumed.

RETURN VALUES
	Returns a transaction handle, or FALSE on error.
