How to start learning PHP MVC and OOP?

I’m starting a new job and it’s custom software, but I’m coming from a wordpress development background.

What about creating a blog from scratch using mvc? As probably any other guy would suggest, you will mostly learn from doing. I did the same when I trying to improve my oop and mvc skills in php (just same as you), I did the same and I still remember what I did. Actually I am a little ashamed what I did but the good part is I know what I did wrong. So my best suggestion is learn oop in theory first if you are not much experienced in it. It will be hard to finish an oop software book but atleast dig internet for some weeks then start your project. And also dont copy paste single line of code. Wish you luck :)
