If your application requires scalability. If the appellation requires heavy IO, use Nodejs rather than PHP. Also, nodejs is very good for real-time chat-applications, video streaming, multi-player games etc. If your application requires MEAN stack or MERN stack, use nodeJs rather than PHP
Both, PHP and Nodejs are popular and both have its own pros and cons. PHP is very mature and popular language while Nodejs is modern and good choice among developers. It depends upon the application requirements when to use PHP and when to use Nodejs.
