To be clear, you're talking about ignoring errors in the sense that PHP continues execution after?
No: once the error has been raised, that's it. They can't be trapped with set_error_handler() either, although they can be detected with some register_shutdown_function() trickery.
Assuming production isn't running some hacked version of PHP, and assuming that everything is running properly to completion, that must mean there aren't any fatal errors. So there's some difference between there and your setup.
