Which language is better....PHP or Node Js?

hey ..I am back with another interesting question....which language is better php or node js.
for understanding this theory you have to first understand the concept of webserver.
What is webserver.....???
webserver is a system which uses https request to perform operations.
let us consider about this ..suppose I have a website like allnonecyberteam.com.If user request any page then first webserver go to open file and then response back......now I think  its clear what is webserver.
now lets consider php and node js.
how does these works.
first consider about php.
php requset pages synchronus type,means it first go to server and open files and then response back
and after that it prepare to handle next requset.
php is slower than node js.
why its slower than node js we will talk about it after understanding concept of node js.
php works on apache web server .php also can run on IIS web server in case of windows machine.
Php is much simpler than node js.

Now consider about Node js.
node js has its own environment.
it uses javascript in backend side so it create its own server.NPM(Node package manager) doesnt need any webserver.
so basically both technology are good but if which language you want to use its depend on your project nature.
if you need centralized server and portablity then use php otherwise if you want speed,real time data and same language across the stack then use node js.
thank you......
