We do almost everything in python, so our stack is basically
python-everywhere (with a bit of C and a bit of PHP).

If you're most comfortable in PHP, I'd suggest writing a data layer in
another language (Java or python) which handles the cassandra requests,
and then making requests back to that from PHP.

That's general advice for any scalable system though - the frontends are
stateless and can be scaled out horizontally (with caching if it fits
your requirements).

If you split your Data layer into parts that are stateless and parts
which aren't then you can load balance the horizontally scalable parts
of that layer using something like haproxy too if you need to.
