PHP for beginners

Good afternoon, habrayuzery .

I would like not to bother you, but still ask for help. Recently I have become interested in html, and indeed the creation of sites. It took more than six months, I was not a professional in html, but I already know perfectly well.

Now it's time to learn PHP. But I don’t even know where to start: reading book guides or php sites.

So the question is: “Where to start for someone who wants to start learning PHP?”

PS Thank you in advance.
