js or php?

from personal experience don't go for one language try to learn other as well. JS, PHP or Python they all are scripting language so if you learn one language better you can easily change with others.

JS is better but as you wish

For myself, I chose js, because it is much more pleasant to write code on it

js for the minecraft, i am a developer of minecraft server. I am also a developer of SA:MP server which have MYSQL ( php )

Both, In my experience
First try to learn JS Html css and then be sure to follow PHP

PHP is the main programming language for server-side web development. I recommend using PHP and JavaScript together for best results.

don't shoehorn yourself - javascript probably more common but for a good job a web developer/programmer should be willing to pick up anything

Learning JS will allow you to do both backend and frontend web development using the same language. I'd recommend this.

js is more powerfull weapon with html, consider js first

Javascript has a TypeScript version which developed by Microsoft. You can use Typescript for both backend and front end. TypeScript works faster than python/ruby.
