The highly controversial GoPHP5 project has come to his finishing mark (actually February 5th) and has been claimed a success by Robert Douglass, one of the creators of the project:
Congratulations are in order. Since the launch of GoPHP5.org, over 100 software projects and over 200 web hosts have come on board to support the adoption of PHP 5.2. As opposed to just a few months ago, it is now easy to find a hosting solution that supports PHP 5, and software developers can turn to the attractive new features that PHP 5 offers without the need to worry that they are leaving their end users without options.
He gives credits to Larry Garfield and Marc Delisle for their hard work towards making the project a success and notes that the project can stand as a successful effort that the community pulled together on to make development and the platforms we build on that much better. Be sure and check out the long list of projects and hosting companies that made the move to PHP5.
