Install The Latest PHP (7.4 in this case)

sudo apt-get install software-properties-common 
sudo add-apt-repository ppa:ondrej/php 
sudo apt-get update 
sudo apt-get install -y php7.4

Disable old PHP version 7.1 and Enable New version 7.4, then restart Apache and check PHP version

sudo a2dismod php7.0 
sudo a2enmod php7.4
sudo service apache2 restart
php -v

If your PHP version does NOT change, it’s likely you have switched PHP version earlier, you’ll need to switch PHP version manually like so:

sudo update-alternatives --set php /usr/bin/php7.4
