PHP Fatal error: Uncaught PDOException: could not find driver

Question

I have been trying to connect to MySQL from PHP using PDO. However, I get this error message:

PHP Fatal error: Uncaught PDOException: could not find

Answer 1

Ok, somehow I had a problem with the extension itself. It helped to reinstall the MySQL extension. Here an example for PHP 7.3:

sudo apt purge php7.3-mysql
sudo apt install php7.3-mysql
sudo service apache2 restart
