Yeah, you would need to write an ORM->NoSQL mapping layer...

ORM is an abstraction on top of SQL. Doctrine has a similar abstraction
(ODM) so you can use Mongo as your backend database. I dont know if its
designed to work with any other NoSQL database so you would have to write
something similar (if you want a higher level interface) or adapt some
existing abstraction code. Of course, your queries might be very simple in
which you can just use straight PHP and whatever API is provided for
Cassandra.

We're using MySQL and eXist. The parts of the application that need to
talk to eXist do not use any ORM layer - its just straight PHP talking
directly to eXist (we're also using memcache so the performance is pretty
good in spite of this).
