An installation of PHP7 and Phan in a small Alpine Linux Docker image.
This project is a simplified version of the complex build process used in Cloudflare's docker-phan.
Phan requires PHP 7.1 and specific PHP extensions to be installed. Sometimes your local version of PHP does not match and users would still need to compile and enable the extra PHP extensions.
By packaging Phan inside a Docker image, we can separate the runtime and configuration of the tool from your application’s environment and requirements.
The easiest way is to create a shell function for “phan” that makes makes it nearly transparent that phan is running inside Docker.
phan() { docker run -it -v $PWD:/mnt/src --rm -u "$(id -u):$(id -g)" fortrabbit/phan:latest $@; return $?; }(You may replace “latest” with a tagged Phan release to use a specific version of Phan.)
If you’re just getting started with Phan, you should follow Phan’s excellent [Tutorial for Analyzing A Large Sloopy Code Base][phan-tutorial] to setup the initial configuration for your project.
All of Phan’s command line flags can be passed to docker-phan.
