Upgrade to php7.3

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install -y php7.3

Check php version

php -v

I hope this helps

If you are using nginx after upgrading php you also need to change the directive in nginx’s default configuration file:

vi /etc/nginx/sites-available/default

Find the line:

fastcgi_pass unix:/run/php/php7.0-fpm.sock;

And change it accordingly (7.3 in this example):

fastcgi_pass unix:/run/php/php7.3-fpm.sock;

Otherwise nginx will still use the old version.

additionally to steps from MattIPv4, to enable apache2 to use php7.3 run these:

sudo a2dismod php7.2

a2enmod proxy_fcgi setenvif

a2enconf php7.3-fpm
