Automated Dependency Updates for PHP Composer Dependencies

Renovate supports upgrading dependencies in PHP's composer.json files and their accompanying composer.lock lock files.

How It Works

1. Renovate will search each repository for any composer.json files.
2. Existing dependencies will be extracted from the relevant sections of the JSON
3. Renovate will resolve the dependency on Packagist or elsewhere if configured, and filter for semver versions
4. A PR will be created with composer.json and composer.lock updated in the same commit
5. If the source repository has either a "changelog" file or uses GitHub releases, then Release Notes for each version will be embedded in the generated PR.

Enabling

Either install the Renovate App on GitHub, or check out Renovate OSS for self-hosted.
