Installing PHP 7.2 on Debian 9

The following steps describe how to install PHP 7.2 using the Ondrej Sury repository.

1. First, update the apt package list and install the dependencies necessary to add a new repository over HTTPS:

   sudo apt updatesudo apt install apt-transport-https ca-certificates curl software-properties-common

   Copy
2. Start by importing the repository’s GPG key using the following curl command:

   curl -fsSL https://packages.sury.org/php/apt.gpg | sudo apt-key add -

   Copy
   Add the ondrej’s repository to your system’s software repository list by typing:

   sudo add-apt-repository "deb https://packages.sury.org/php/ $(lsb_release -cs) main"

   Copy
3. Now that we have the ondrej’s repository enabled on our system, we can install PHP by specifying the version we want to use:

   sudo apt updatesudo apt install php7.2-common php7.2-cli

   Copy
4. Verify the installation, by running the following command which will print the PHP version.

   php -v
