ibase_trans
(PHP 3>= 3.0.7, PHP 4 )
ibase_trans -- Begin a transaction
Description
resource ibase_trans ( [int trans_args [, resource link_identifier]])
Begins a transaction.
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.
Note: The behaviour of this function has been changed in
PHP 5.0.0. The first call to ibase_trans() will not return
the default transaction of a connection. All transactions
started by ibase_trans() will be rolled back at the end
of the script if they were not committed or rolled back
by either ibase_commit() or ibase_rollback().
Note: In PHP 5.0.0. and up, this function will accept multiple
trans_args and link_identifier arguments. This allows transactions
over multiple database connections, 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() and ibase_prepare().
