You can turn error_reporting off, see
http://de.php.net/manual/en/function.error-reporting.php

or you can define an error-handler which is called on warnings and
errors, see http://de.php.net/manual/en/function.set-error-handler.php

If you are using php5 ibase_set_event_handler() is the best solution,
see http://de.php.net/manual/en/function.ibase-set-event-handler.php
