ibase_trans
  Begin a transaction
  
 
 
  Description
  
   resource ibase_trans
    ([ int $trans_args
   [, resource $link_identifier
  ]] )
  
   resource ibase_trans
    ([ resource $link_identifier
   [, int $trans_args
  ]] )
  
  Note: 
   
    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: 
   
    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.
