phpDocumentor review
A focused, open-source choice for PHP API documentation and project guides.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
phpDocumentor is an open-source documentation generator for PHP projects. It analyzes PHP source code and DocBlock comments to create API documentation, while also rendering hand-written reStructuredText guides alongside class documentation. Developers and teams maintaining PHP libraries or applications can run it locally on Linux or macOS through a PHAR, Docker image, Composer package, or Phive installation. Its focus is source-based PHP documentation rather than hosted interactive API publishing.
The documentation workflow covers more than class and method reference pages. phpDocumentor can create UML class diagrams with PlantUML or GraphViz, add full-text search to generated documentation, and use customizable templates and navigation. Caching can support repeated documentation generation, while GitHub Actions and Docker integrations fit continuous-integration workflows. Composer and Phive provide additional installation paths for PHP teams that already manage project tooling through those ecosystems.
phpDocumentor is a strong fit when the source code and DocBlocks are the primary documentation inputs, and when a team wants control over local generation, templates, and delivery. It is less suited to teams seeking OpenAPI import, interactive API references, built-in code samples, custom domains, or a hosted platform. The published configuration supports multiple documentation versions in its model, but current projects are limited to a single configured version. Choose it for focused PHP API documentation and companion guides; consider an alternative when interactive, hosted, or broader API-specification workflows are central.
