PHP vs Node.js for video sharing website, which would make more sense? [closed]

I'm trying to create a similar website like YouTube, where people can upload and share videos, my question is for the backend should I use PHP or Node.js, which makes more sense? From research I can see Node.js is faster, but PHP is easier? Is there any negatives to just using PHP? and if so what are the positives of switching and using Node.js instead? Thanks for your help much appreciated.
