Update Ubuntu

Add the PHP repository

You can use a third-party repository to install the latest

Next, add the PHP repository from Ondřej: add-apt-repository
ppa:ondrej/php

And finally, update your package list: apt-get update

After you’ve added the repository, you can install PHP 7.2
with the following command: apt-get
install php7.2

And that’s it. To check if PHP 7.2 is installed on your
server, run the following command: php -v

Install PHP 7.2 modules

You may need additional packages and modules depending on
your applications. The most commonly used modules can be installed with the
following command:

·       
apt-get install
php-pear php7.2-curl php7.2-dev php7.2-gd php7.2-mbstring php7.2-zip
