Answer 1

New versions of WAMP seems to install both MySQL and MariaDB. And when I logged in through the phpMyAdmin, I saw that the MySQL is using the port 3308.

So in my PHP code, instead of using just localhost for my database hostname, I added the port to it like this: localhost:3308 and it worked.

$db = new mysqli('localhost:3308', 'root', 'password', 'db_name');
