Christopher Jones has a quick new comment over on his Oracle blog about the release and contents of Sara Goleman's book, Extending and Embedding PHP.
Like all good books, you should read this even if you never plan to follow the title. What you will gain from the text is a better understanding of PHP and knowledge about how a large program (PHP itself) has been designed and works. I'm reminded of Lions' Commentary on Unix (though Sara's book does not reproduce all the code of PHP!) because this is a ground breaking book.
It's always good to get a better idea of what's going on behind the scenes. Too many people just use PHP and think new versions just magically appear. In truth, there are a huge number of developers working on new features and fixing bugs to help make PHP, the language, a better place. And, thanks to Sara, the work those folks do gets a bit more recognition.
