New this morning (well, new to us) are two PDF files from a European developer, Harald Radi (from Austria, I believe - http://www.nme.at) about "Creating Multi-Tier Web Applications with PHP".

One of the PDF files is his presentation from the PHP Conference 2002 on the topic, while the other just appears to be a book excerpt on the same topic. They contain about the same amount of information, but the presentation seems to include more code examples for the architecture that he has laid out. It involves using PHP, sessions, and Smarty to act as a presentation layer on top of his RDBMS, and Java/COM/.NET/CORBA objects and scripts. He even gives some code examples on each of the underlying technologies to give you an idea of how they all work together.

I see more and more articles and presentations like this - people actually taking the time to plan out an architecture with PHP as the central focus. It's a nice change from the "infant" stages that most PHP scripts seemed to be working at not too far in the past.

Thanks to Ewald for the links...
