Symfony2和ODBC支持

We are on the early stage of developing an application and we're using Symfony2 framework to do the job. We need to connect to Oracle database. It works great with oci8 driver, but unfortunately it seems that our company doesn't support oci8 and can't install that PHP extension on the production servers. They recommended using ODBC for PHP instead.

Well... now we're stuck. Is there any good way for Symfony 2.8 to work with ODBC? Is this somehow supported? Did anybody actually try this setup?
