There are some PHP developers out there that see PHP as a sort of constant "work in progress" with issues all around - confusing function names, non-intuitive features, and more. So, a group has been formed to help clean things up a bit - the ogoproject.
The ogo project aims to clean up PHP, starting with fixing the inconsistent (and difficult to remember) function names. PHP needs clear naming conventions, and it needs to stick to them. We will offer a temporary fork until function name changes are agreed on, and sensible backwards and forwards compatibility is in place. Then we can get our changes merged into the main branch.
They've already posted some suggestions for a few things, including conventions they're looking to follow and a list of new function names changed according to these new conventions. There's also a downloads and forum section that will soon have content.
If you're interested in getting involved, stop by the #ogoproject channel on the Freenode IRC network and see what's going on.
