What is a good, or the best, intermediate / advanced php book to buy

[mrmbarnes]

Hi All

I have been doing php web development for about 8 to 12 months now. I started with Kevin Yanks book, which I highly recommend to anyone starting off. I have another book a bit more advanced however I have moved to a level where I need more information and more training/learning.

My main interests at the moment is learning more advanced functions, advanced user management, member areas and credit card processing, advanced form submitting and generally doing things quicker and easier.

I’m sure there is heap more stuff out there that I don’t even know about as well.

Basically I would appreciate any suggestions on what is a good, or the best, intermediate / advanced php book to buy.

Thank you all for your help once again.

I've enjoyed reading O'Reilly's PHP Cookbook

Well Harry Fuecks PHP Anthology covers all that (except credit card processing) and is available through SitePoint at a very decent price
