Hello pierrefar. Yes, the most important client libs will support (many already do) 1.1 sorted sets, MSET and MSETNX commands (Multi keys set in a single command atomically), and the other features once 1.1 will be released.
But about PHP, I've good news, there are two new fully featured high quality implementations of the Redis protocol for PHP:
Also the PHP C module got two new developers and is now much more stable, supporting the full 1.0 protocol AFAIK: http://github.com/owlient/phpredis
So the client libs arena is getting better and better fortunately. Other good quality client libs are for Ruby, Java, and Go Language. Python is getting better with the time too.
I'm actually writing a CMS using Redis and absolutely need SETNX (which one current PHP-only lib supports well). I would like to move to a compiled PHP module so that I get a nice performance boost.
Coupled with this new log-based persistence, I'll be more comfortable with the whole set up.

Predis (http://github.com/nrk/predis/) and Rediska (http://rediska.geometria-lab.net/). Both with support for consistent hashing.
