IlluminateDatabaseQueryException could not find driver Laravel

I deploy a laravel project on an apache server on a Debian 10 machine. The database is an MySQL deployed on another debian 10 machine on the same network.

I can go to the connection interface of the application but when I connect this error appears :

IlluminateDatabaseQueryException
could not find driver (SQL: select * from `users` where `email` = [e-mail] limit 1)

I have already tried these commands :

php artisan migrate
sudo apt install php-mysql
sudo apt install php7.4-mysql
sudo systemctl restart apache2
composer require doctrine/dbal
composer update

these commands work but do not solve the problem.

and I already tried to comment and uncomment this line in the php.ini :

extension=pdo_mysql

in php-m i have PDO and pdo-mysql

and i have restart my server with :

systemctl restart apache2

after modification

Answer

I finally found the solution infact the php version used by apache was 7.3 and not 7.4 with :

<?php phpinfo() ?>

however when I did:

php --version

the version was indeed 7.4. I followed this tutorial to change the version https://tecadmin.net/switch-between-multiple-php-version-on-debian/?amp and it works
