Provides a PHP 7.1 docker image based on our Alpine Linux 3.7 base image.

This image can be used as a base for the testing and deployment of PHP applications.

Included scripts:

Script	Purpose
php-ext.sh	Enables, disables or shows PHP extensions
php-extensions.sh	Provides helper functions for getting available and default PHP extensions
setup-gitlab-token-auth.sh	Configures git and composer authentication via GitLab CI token
setup-nginx.sh	Configures the built-in nginx web server

Included tools:

sami	Sami API documentation generator	https://github.com/FriendsOfPHP/Sami
phpcs	PHP CodeSniffer	https://github.com/squizlabs/PHP_CodeSniffer/

For running the PHP applications, a locked default user project with UID 1000 is created.

To build the docker image, do not forget to adapt the base image version in Dockerfile where necessary.
