I am interested in PHP and OOP and I am looking for a nice PHP book with lots of examples and simple, easily understandable texts. I know the basics, so I am not a complete beginner, but I am not very advanced, too. I tried reading PHP Objects Patterns Practice by Matt Zandstra and understood maybe the half of it, but then it became complex and hard to understand for me. I tried learning patterns of design but some of them are difficult.
Please, advise me which book to read and maybe some sites where I can see OO codes of applications. I am also searcing of some simple task or projects to write in order to practise and understand things better.
Tnank you very much in advance! :)
