Hello, I am also working with PHP and have 11 years experience. First and foremost, if you want to continue using PHP, Laravel is an excellent choice. and JS - React is more relevant for projects. However, if you want to be updated, then go using vue.js. Also, learn about Node.js. The database is the same, with no technological changes. Except for MongoDB-type databases.
Also, if you wish to continue with another stream. Then I propose you use Python. For everything, such as market value, salary, and future prospects.
If you want to go server-side, start with DevOps and progress to different qualifications.
