🏗️ Setting up a development build of phpBB

To run an installation from the repo (and not from a pre-built package) on a local server, run the following commands:

  • Fork phpbb/phpbb to your GitHub account, then create a local clone of it:
    git clone
  • Install phpBB's dependencies (from the root of your phpbb repo):
    cd phpBB
    php ../composer.phar install

Alternatively, you can read our Vagrant documentation to find out how to use Vagrant to develop and contribute to phpBB.

📓 Documentation

phpBB's Development Documentation contains all the information you'll need to learn about developing for phpBB's core, extensions and automated testing.

🔬 Automated Testing

We have unit and functional tests in order to prevent regressions. You can view the bamboo continuous integration here or check our GitHub Actions below:
