Can't access phpmyadmin and local localhost:8000 with two errors for each of them

Recently reinstalled Ubuntu 21.04 on my computer and installed php8 and Nginx. I run the server for Laravel and when I go to localhost:8000 I got this error:

Illuminate\Database\QueryException
could not find driver (SQL: select * from `sessions` where `id` = 
k8TiDjzbt96oJgAhUkwhOzJO0dYUcctBdLCLuvTK limit 1) 
http://localhost:8000/

I think this error comes from PDO.

and when I go to localhost/phpmyadmin I got this error:

404 Not Found
nginx/1.18.0 (Ubuntu)

When I type php -m in terminal:
