On PHPKitchen today, Demian Turner has posted a a few words about one of the latest PHP-related books he's read, "PHP5 Objects, Patterns, and Practice" from APress.
I found Matt, who comes from a Java background, really hit the nail on the head, this book is an enjoyable read. While the first few chapters make allowances for readers who don't have a lot of exposure to OOP, the rest is quite a stimulating read, helped along in no small part by Matt's excellent unambiguous writing style.
I recently read Matt Zandstra's PHP 5 Objects, Patterns, and Practice and thought I'd say a few good words about it for those who haven't been recommended yet. A lot of good PHP5 books have come out recently, eg something like PHP 5 Power Programming is an excellent resource for the finer points of charset issues, utf8 in PHP, timezone gotchas. But it's quite unusual in PHP circles for a book to come out that gives overall sound advice on application design.
He also mentions other topics that the book covers, things like the Composite pattern, Phing, PEAR, and the Reflection API.
