shivammathur/setup-php: README-based editorial guide

shivammathur/setup-php describes itself in the README as "GitHub action to set up PHP with extensions, php.ini configuration, coverage drivers, and various tools.". This article keeps to facts that can be checked in the repository. Stars, forks, and promotional badges are signals of attention, not proof of quality. Under "README", the README says: Setup PHP with required extensions, php.ini configuration, code-coverage support, and various tools like composer in GitHub Actions to see how to use this.. That establishes the project's stated boundary, not a production test.

The README's "Self-Hosted Runners" section gives a useful starting point for deciding whether the project fits: Operating systems based on the above Ubuntu and Debian versions are also supported on a best effort basis.. If that problem is not yours, popularity is a poor reason to adopt it. Project names, commands, and component names are kept as written so a reader can return to the primary source without guessing at terminology. Another checkable README item is: Refer to the self-hosted setup to use the action on self-hosted runners.. It can shape a first test, but it does not replace testing in the intended environment.

The operating model is spread across sections such as "GitHub-Hosted Runners". The source evidence includes: | Virtual environment | Arch | YAML workflow label | Pre-installed PHP | |---------------------|---------|------------------------------------|-------------------| | Ubuntu 26.04 | x8664 | ubuntu-26.04 | PHP 8.5 | | Ubuntu 24.04 | x8664 |. This article does not turn missing architecture, performance, or security details into claims. A real deployment still needs a look at the repository layout, configuration files, and release history.

Start installation from the README's documented entry point. A command that can be checked in the source is: - name: Setup PHP with tools pinned to a checksum uses: shivammathur/setup-php@v2 with: php-version: '8.5' tools: composer:2.9.8@sha256:59b2c50e10cafa0d8efc19ede9a326d782f096c674a26baf98cf042ce23de890 When the README contains no runnable command, this article does not invent one. Open its ":cloud: OS/Platform Support" section and confirm system dependencies, default ports, and first-run initialization before using a public server.
