PHP is server-side. Basically, Angular handles all the viewing etc inside the browser and on the same page, sending requests to the backend API (e.g created via PHP) to handle database requests and so forth. Angular and PHP serves two completely different functions and can be used together, not in place of one another.
On the back-end, you can use many languages, including Java, PHP, C#, and (only since a few years) JavaScript with NodeJS. The main adavantages of using JavaScript with NodeJS on the back-end are: Since you anyway need to be good at JavaScript programming for doing your job on the front-end, if you are also using it on the back-end, you only have to master a single language (and its tooling), instead of two. That's a huge benefit.
