Object Oriented PHP Book

I hope Jeffrey doesn't mind this little "advertisement", but I'm working on a book with phpacademy's founder Alex Garrett. It should be out within the next month or two.

Until then, I'd recommend this: http://www.nostarch.com/oophp.htm

I'll have a look at that when it's out! Is the other book worth getting because it was published in 2006?

That's the issue that I've faced @devjack, so many of the published books etc are either old or just contradict each others methods/practises. Anyone recommend any others, I'd also be very grateful.

It's out of date, but "PHP Objects, Patterns and Practice" was a popular choice. I'm still reading it, but I'd imagine the bits on design patterns are still relevant.

I'll do a series on basic OOP principles soon.

+1 for @dabernathy89 recommendation PHP Objects, Patterns and Practice. Sure it is old, but all of the foundation stuff use relevant and pretty easy to digest.
