How do you assess your knowledge level in PHP and which areas of programming in this language are you most familiar with?

My PHP knowledge level can be considered as middle. I am well familiar with the basics of syntax, OOP, working with databases through PDO, form handling, and sessions, as well as popular frameworks like Laravel and Symfony. I can write clean, maintainable code, understand MVC principles and REST API. I am also familiar with Composer for dependency management and basic testing in PHP.
