On the echolibre blog there's a recent post looking at the recent meeting of the (Recommended) Standards Group at this year's php|tek:

This post will briefly discuss the formation of a Recommended PHP Standards Group, as put forward by a meeting of PHP developers at the conference. As would be expected, a bit of controversy surrounds this proposal, but my hope would be that it would be accepted and grow within the global PHP community in the coming years.

He talks about those in attendance and a sneak preview of some of the standards they're talking about - like those dealing with namespacing and exception naming.
