PHP 5.5 has recently been released as an ALPHA release, meaning there are still bugs, code is being tested and features being added. With the 5.5 release, many of us PHP developers have a few wonderful new features that we should be taking advantage of almost immediately.

He gives brief introductions to these two new features, including some code examples (but getting a bit more into the generators side of things). You can find out more about these two features and how to implement them when PHP 5.5 comes around from the PHP sitel: generators and finally (actually from the PHP wiki).
