I'd recommend
sitepoint's books that were mentioned above for PHP as I found the organisation of code was quite good.
The code from the first examples were expanded on and used again as the chapters progressed. It was mostly Object oriented and after working from the examples, I think the code I produced was of a better quality than before.
At the moment I'm really enjoying working with
cake which is an MVC php library. It may not suit you if you're just finding your feet with php but learning from other people's goog code can be very useful.
Good luck.
