I have 8 years of PHP experience. Let me explain to you. While you can build a static website with Apache Struts or PHP, you must add javascript if you want to build complex sites anyway, for example: Facebook, Twitter, Tiktok,... In the past, everyone used jQuery, but jQuery and ajax can't build complex sites. You will end up with too many Ajax + dynamic elements + bad practices and can't maintain them if you use jQuery. Finally, you'll end up using React for easy to maintain. And you'll have to wait to load React + related packages => it is slow for initial render => and SSR solved the problem. Also, you just need a single team to build a complex application while using React instead of backend + frontend as traditionally.
