You don't know PHP at the level of Junior PHP developer
Probably, you've only started learning or didn't pay enough attention to the main subjects when studying the language. Don't be upset: remember your mistakes, read theory, train on problems - and try to take the quiz again when you're ready! The developer's way is not easy, but the main thing is to devote enough time to learning and you'll definitely succeed! Show the quiz to friends: do they know PHP at Junior level?
You know the basics of PHP. This is not bad, but not enough for the level of Junior PHP-developer
You're good at the basics and can create a simple project, but there are some important gaps in your knowledge you should close before going on. Read the chapters of a self-help textbook on subjects where you made mistakes in the quiz, train on problems and when you're confident in your knowledge take on more serious subjects. Good luck!
