PHP project architecture examples
Interactive architecture diagrams of 221 open-source PHP repositories with a GitDiagram architecture diagram, most stars first. Each diagram shows the project's main components, how they connect, and links every part to its file on GitHub.
Across the 118 most-starred PHP projects here, the median diagram has 21 components. 63% draw a data store (most often files on disk, a cache and MySQL or MariaDB), 9% have a command-line interface and 19% a web interface.
34% have a plugin or extension system and 11% draw a queue or event bus.
The files their components link to most are index.php (27), User.php (10), Controller.php (8), app.php (6) and database.php (5).
Group names that recur: “platform services” (9), “administration” (5) and “public api” (4).

Counted over GitDiagram's stored diagrams of public repositories, from the names their components and groups carry and the files they link to; the rules are the ones in the 2026 open-source architecture report. Stars are GitHub's when the diagram was last made. Rebuilt daily: hubs grow as more repositories' languages are known.
