What it is
phpDocumentor is a free, open-source, self-hosted tool for analyzing PHP source code and DocBlock comments to produce API documentation. It can generate UML diagrams, parse Markdown and reStructuredText, and insert API-documentation sections into reStructuredText material. The site says full-text search works offline and describes CI integration through a GitHub Action or Docker image. Installation options include Docker, Phive, and a PHAR file; standalone installation requires PHP 8.1.2 or newer plus mbstring, while PlantUML is optional. The official Docker image supplies dependencies locally. The project also offers Composer-installable components for parsing, rendering, type resolution, and PHP reflection. It runs on Linux and macOS. Its Docker Hub overview does not actively support direct Composer installation because dependency conflicts may occur. No paid plans are listed; the plan costs nothing.
