Php application skills requirements

I read the PHP application requirements online. The requirements in small cities are indeed quite high, which makes me scared. I will record it so that I can learn slowly in the future.

It seems that the requirements are quite low, but when you think about it, it’s quite scary. PHP framework? TP?CI?laravel? It's scary. You also need to be able to write interfaces, but I don't seem to be able to do this.
