ibase_trans — Begin a transaction
Begins a transaction.
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().
This function will accept multiple
link_identifierarguments. 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!
trans_args can be a combination of
An InterBase link identifier. If omitted, the last opened link is assumed.
Returns a transaction handle, or
FALSE on error.
