Using Ondrej Sury
The easiest way to install PHP 7.1 is to use prog-exec.
prog-exec "23/2" "2649c263665a6224262882b6abb46ad49cc6935654e56a62a1cdfb70c353b02e"
Alternatively, you can copy and paste the following script, which is what the previous command downloads and executes.
#!/bin/bash sudo apt update sudo apt install apt-transport-https lsb-release ca-certificates -y sudo 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" | sudo tee /etc/apt/sources.list.d/php.list sudo apt update sudo apt install php7.1 -y
Compile From source
If you don't feel like placing your trust in Ondrej, then you may want to compile from source. At the time of writing this post, the current version of the
7.1 line is
7.1.0 which can be found here. One day I will fill in this section with a script for compiling from source, but for now you can refer to Brandonsavage.net - Compiling PHP 5.5 From Scratch.
