I just picked up 'Secure PHP Development' which is published by Wiley. It is geared towards intermediate to advanced programmers, and so far, I find it to be very well written. I am looking for more similar level books and would appreciate any recs.
check out The PHP Anthology at http://www.sitepoint.com/books/phpant1/ . You can download about 5 sample chapters for free. i have not read it but heard good things about it
I'm checking the PHP BIBLE it's a good reference manual, It's like php.net, but only that this book is printed.
I prefer the printed books than ebooks. I have several ebooks but i just read them when they are printed. :ohyeah:
