In this post I am going to explain to you how we can install PHP 7.3 in your Ubuntu. PHP 7.3 is under development and going to release soon, but we can install PHP 7.3 and test all the feature in the development phase using ondrej/php.

Please follow below steps to install the latest version of PHP 7.3

sudo apt-get update
sudo add-apt-repository ppa:ondrej/php

Step 2. Now we can add the latest version of PHP to do that run below command in terminal
