Pádraic Brady has a suggestion for all of the PHP readers out there - two articles in the latest edition of php|architect magazine, the May 2007 edition:

The two that stick in my mind are Jim Delahunt's "Unicode and PHP: A Gentle Introduction" and Jeff Moore's "Test Pattern: Model View Controller". Both are something those seeking illumination on these topics should certainly read.

The first presents an introduction to one of the hottest topics in the PHP world - Unicoding - including a few same scripts to get you going. The second article, a look at the Model/View/Controller pattern that really gets more to what the pattern is about rather than just talking about its structure.
