Freelance backend. What does a beginner in php need to know in order to start earning? Where to begin?

Question

PHP

Good day.
I have been learning php and wordpress for half a year now, and before that I was fond of layout.
I did it as a hobby. Now I decided to try to make money.
I went to freelancing, I saw a lot of things I didn’t understand and realized that I didn’t know much.
I decided to turn to a resource that more than once helped out with its answers.
And so, where to start? What to learn? Which framework`s to learn in priority?
What kind of puzzles to learn to solve on the basis of knowledge of the basics of php.
I think a lot of beginners ask these questions after they have learned the basics of "What next?"
