I want to ask if I am learning php backend and have a good knowledge of html css. Let me ask if I have to be good at html css, so should I learn php or like I study php?
To be frank, HTML and CSS should be well mastered when learning PHP. As JS is to the client, PHP is to the server. They’re both once only script, essentially. JS generates DOM stuff, PHP generates request responses.
Again, to be frank, PHP is an easy language to learn, for some, but for most it is frought with learning hurdles. Every detail matters in this language, else it responds with a code 500. The user sees a white screen since that’s what is sent back down.
