This is a PHP issue and not CodeIgniter. See this SO question – DFriend

Install php extension for mysql.

use this command

sudo apt-get install php-mysql

After installation restart apache with this command

sudo service apache2 restart

update

If sudo apt-get install php-mysql

not work for you then you should use

sudo apt-get install php7.2-mysql

 extension=mysqli.so
