Tobias Schlitt shares some of his toughts on one of his latest in a list of books to read - Exporing PHP.

Although I did not read it, yet, I'd like to recommend it to you, since I think to know the authors good enough to believe they write good books.

In short, "Exploring PHP" is a roundup about advanced PHP programming experiences, covering different topics like: Event driven programming in PHP, Generation of 3D graphics, Refactoring and Migration, PHP6.

From the little that he's looked into the book, he can already tell it's a good resource and is recommending it based on that and the authors it comes from.
