Hi nikic. Thanks for the feedback! (I'm the author of that article). The O'Reilly editors made a few changes to the wording without my review that make it more ambiguous as to what features were introduced in what version. I agree as is it can be confusing. But the point is that the latest version of PHP provides all of these features. The variadic function statement was an error on my part and it has since been corrected in the article.
I agree. It's very much in a v1.0 form right now. Once I move over to GitHub Pages, I hope to add more links to tutorials and code samples without bloating the document itself.
I think it's less about being "superior" than standardizing on a common style. Makes it easier to get up and running with someone else's code. But if your team agrees on a common but different style, that's fine too. It accomplishes the same goal. I'm only suggesting the official standard for new PHP developers.
Looks promising! I've actually been developing my own Sinatra clone in PHP5. I've called it "Slim". It has RESTful GET, POST, PUT, DELETE routing. It has before and after callbacks. It has Page Not Found handling, halting, helpers to set custom response codes, and easy-to-extend templating (use Smarty, Twig, or whatever you want). See more at:
