Do websites still use JQuery and/or PHP?

Question

I saw some posts the other day about people talking about how JQ and/or PHP are starting to get outdated. So I wanted to ask the following:
Are PHP and JQ REALLY getting outdated?
And if so; what is the alternative for these assets?

PHP is used by 78.9% of all websites with a known server-side programming language

With jquery, it has lost most of its usefulness with the evolution of js and growing browser support for javascript. Here's a nice collection of its replacement. Nevertheless if you have to deal with older js code written by someone else in jquery, it certainly pays off to know the syntax.
