Standalone PHP Solid Server

PDS Interop Project stage: Development License Latest Version standard-readme compliant Maintained

Standalone Solid Server written in PHP by PDS Interop

Table of Contents


The Solid specifications defines what makes a “Solid Server”. Parts of those specifications are still likely to change, but at the time of this writing, they define:

  • Authentication
  • Authorization (and access control)
  • Content representation
  • Identity
  • Profiles
  • Resource (reading and writing) API
  • Social Web App Protocols (Notifications, Friends Lists, Followers and Following)


To install the project, clone it from GitHub and install the PHP dependencies using Composer:

git clone git:// \
    && cd php-solid-server \
    && composer install --no-dev --prefer-dist

At this point, the application is ready to run.


The PHP Solid server can be run in several different ways.

The application can be run with a Docker image of your choice or on a local environment, using Apache, NginX, or PHP’s internal HTTP server. The latter is only advised in development.

For security reasons, the server expects to run on HTTPS (also known as HTTP+TLS).

To run insecure, set the environment variable ENVIRONMENT to develop. This will prohibit the application from running in production mode.

Docker images

When running with your own Docker image, make sure to mount the project folder to wherever the image expects it to be, e.g. /app or /var/www.

For instance:

export PORT=8080 &&        \
docker run                 \
   --env "PORT=${PORT}"    \
   --expose "${PORT}"      \
   --network host          \
   --rm                    \
   --volume "$PWD:/app"    \
   -it                     \
   php:7.3                 \
   php --docroot /app/web/ --server "localhost:${PORT}" /app/web/index.php

Or on Mac:

export PORT=8080 &&        \
docker run                 \
   --env "PORT=${PORT}"    \
   --expose "${PORT}"      \
   -p "${PORT}:${PORT}"    \
   --rm                    \
   --volume "$PWD:/app"    \
   -it                     \
   php:7.3                 \
   php --docroot /app/web/ --server "localhost:${PORT}" /app/web/index.php

Local environment

How to run this application in an Apache, NginX, or other popular HTTP servers falls outside the scope of this project.

For development purposes, the internal PHP HTTP server is explained below.

Built-in PHP HTTP server

For development purposes a Composer serve-dev command has been provided. This will run the application using PHP internal HTTP server.

To use it, run composer serve-dev in the project root.


By default, the application is hosted on localhost port 8080. So if you visit http://localhost:8080/ with your browser, you should see “Hello, World!”.

Both the HOST and PORT can be configured before running the command by setting them in the environment, for instance:

HOST='solid.local' PORT=1234 composer serve-dev

This command can also be run through a docker container, for instance:

export PORT=8080 &&     \
docker run              \
   --env "PORT=${PORT}" \
   --expose "${PORT}"   \
   --network host       \
   --rm                 \
   --volume "$PWD:/app" \
   -it                  \
   composer:latest      \

Running solid/webid-provider-tests

Due to you should run, in one terminal window:

HOST= composer serve-dev

and in another you run the webid-provider-test as:

SERVER_ROOT=http://localhost:8080 ./node_modules/.bin/jest test/surface/fetch-openid-config.test.ts

The current dev branch of php-solid-server should pass roughly 7 out of 17 tests.
