Back when I was learning PHP, I created a nice collection of resources. I figured, "Why shouldn't anyone benefit from these?" I review each one as I publish it, hoping people will benefit from it. I update any areas that need updating.
These courses will teach you the basics, but if you don't code, you'll forget them. You have to keep creating. Whether it works or not, keep creating. Don't forget to support open source too :)
At the same time php documentation Don't forget to read too.
