是否有完善的PHP命名空间命名约定？

Question

So far, I've seen many different naming conventions used for PHP namespaces. Some people use PascalCase\Just\Like\For\Classes, some use underscored\lower_case ames, some even use the Java convention for package names: com\domain\project\package.

The question is very simple -- can any of these (or other) conventions be called well-established? Why? Are any of them recommended by authorities like Zend or the developers of well-known PHP frameworks?

A PHP Standards Working Group made up of contributors to many different PHP frameworks and projects came up with the following proposal for appropriate namespace usage:
