Web Spider & Search Engine.



ibase_rollback — Roll back a transaction


boolean ibase_rollback([trans]);
int trans (optional): Connection or transaction handle


TRUE on success, FALSE on error


Rolls back an open transaction so that changes you have made to the database are undone as though they were never made. Returns TRUE if everything went well, FALSE if unsuccessful. Trying to roll back a transaction that already has been committed or rolled back is considered to be an error and therefore returns FALSE.

The behaviour of this function varies slightly depending on the optional parameter trans . The 3 possible cases are:

  • No parameter given: roll back the default transaction on last opened connection.

  • Connection handle: roll back the default transaction on specified connection.

  • Transaction handle: roll back the specified transaction.


Available in PHP 3 since 3.0.7, PHP 4 since 4.0RC1
