The phpRiot.com site i show to quite a few good articles, tutorials, and resources on PHP, but had fallen off as far as new postings. According to this new post, though - that's about to change.

We haven’t posted an article for over a month, so please bear with us while new content is finalised. There are several articles in the pipeline, including articles to do with using database abstraction and database objects. We hope to post these in the coming weeks.

Additionally, there is supposed to be third part to the Nested Trees article series. This hasn’t yet been written, but hopefully this will make an appearance in the next month or two!

They also make a mention of PHP 5.1 RC1 being released and Smarty 2.6.10 - but keep your eyes open for some of the new content to come from this site...
