What I mean is - could I have a default transaction that is READ ONLY (for example)? I don't see any php.ini parameter related to transactions, and in the "Predefined constants" section there is
IBASE_DEFAULT: The default transaction settings are to be used. This default is determined by the client library, which defines it as IBASE_WRITE|IBASE_CONCURRENCY|IBASE_WAIT in most cases.
