How To Install Php 7.1 On Debian 8

Posted on Tuesday 19th September 2017

For installing PHP 7.2 see https://www.chris-shaw.com/blog/installing-php-7.2-on-debian-8-jessie-and-debian-9-stretch

I found this week that I needed to upgrade my main server to PHP 7.1, after finding it would slighly different for Debian systems, it made sence to post another article.

To install php 7.1 on debian, we will be using Ondřej Surý, repository again, but this time the one for Debian rather than Ubuntu.

All we need to do is add the PPA Repository to Debian

Adding this Repository to your system

You can update your system with packages from this PPA by adding ppa:ondrej/php to your system's Software Sources.

apt-get install apt-transport-https lsb-release ca-certificates
wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list
apt-get update

Installing PHP

Now as we have ondrej's PPA available as a source, we can go ahead and install PHP as we normally would with apt-get, we just need to specify the version we want to use.

sudo apt-get install php7.1

Installing Some Additional Packages

sudo apt-get install php7.1-cli php7.1-common php7.1-curl php7.1-gd php7.1-json php7.1-mbstring php7.1-mysql php7.1-opcache php7.1-readline php7.1-xml

Verify Install

To verify PHP7.1 is installed, just run the following to see the version you are using.

php -v
