I have been always confused when I want to start learning PHP. I got afraid of learning any bad habbits or things that could lead to unsecure applications. If you can help and hope you can, I would like to ask you experts in PHP to help me and put a roadmap for me from the beginning. It would be better if it is a series of books so when I finish a book I go to the next or a series of videos or whatever. No worries about how much the books may cost, most importantly that I will learn the right things.

Thanks.
