|Subject||Re: Choice of PHP Driver for Doctrine Implementation|
We are the maintainers for both drivers and we accept contribuitions like yours in the frameworks area
both drivers will be supported pdo_firebird is a lot easier to use in orm , but if you need the low level firebird api features then ibase is the way
My vote is to go with pdo_firebird first (i saw that you have already started with it) and if is not enough then go deeper with ibase driver
After you finish firebird driver and create a pull request you can ask for testers and we will announce on this list and firebirdnews / reddit ...
Also i'm interested in drupal8 driver for firebird
