PHP Book recomendation

[poil11]

I want you to give me a recomendation on the next php book that i would like to buy. I have semi experience with php now, but i am looking for a semi Advanced book. i have already read and understand pretty much in Core PHP Programming, by leon atkinson. any help or advice is greatly appreciated. thank you.

Professional PHP Programming by Wrox is very good, it will have some stuff in it that you already know. I picked up someone elses copy and learnt a few things I didn't know and I'd been using PHP for a year at that time every day of the week.

I second Kar's recommendation - I started learning PHP from Kevin Yank's tutorial, once I got through that I bought Professional PHP Programming and it really did improve my knowledge of PHP.
There are also a couple of 'Case Study' chapters which show you how to make a specific program or type of program.
