## :cloud: OS/Platform Support

Both `GitHub-hosted` and `self-hosted` runners are suppported by `setup-php` on the following OS/Platforms.

### GitHub-Hosted Runners

|Virtual environment|YAML workflow label|Pre-installed PHP|
|--- |--- |--- |
|Ubuntu 16.04|`ubuntu-16.04`|`PHP 5.6` to `PHP 7.4`|
|Ubuntu 18.04|`ubuntu-latest` or `ubuntu-18.04`|`PHP 7.1` to `PHP 7.4`|
|Ubuntu 20.04|`ubuntu-20.04`|`PHP 7.4`|
|Windows Server 2019|`windows-latest` or `windows-2019`|`PHP 7.4`|
|macOS Catalina 10.15|`macos-latest` or `macos-10.15`|`PHP 7.4`|
|macOS Big Sur 11.0|`macos-11.0`|`PHP 7.4`|

### Self-Hosted Runners

|Host OS/Virtual environment|YAML workflow label|
|--- |--- |
|Ubuntu 16.04|`self-hosted` or `Linux`|
|Ubuntu 18.04|`self-hosted` or `Linux`|
|Ubuntu 20.04|`self-hosted` or `Linux`|
|Windows 7 and newer|`self-hosted` or `Windows`|
|Windows Server 2012 R2 and newer|`self-hosted` or `Windows`|
|macOS Catalina 10.15|`self-hosted` or `macOS`|
|macOS Big Sur 11.0|`self-hosted` or `macOS`|

- Refer to the [self-hosted setup](#self-hosted-setup) to use the action on self-hosted runners.
- If the requested PHP version is pre-installed, `setup-php` switches to it, otherwise it installs the PHP version.

## :tada: PHP Support

On all supported OS/Platforms the following PHP versions are supported as per the runner.

- PHP 5.3 to PHP 8.1 on GitHub-hosted runners.
- PHP 5.6 to PHP 8.1 on self-hosted runners.

|PHP Version|Stability|Release Support|Runner Support|
|--- |--- |--- |--- |
|`5.3`|`Stable`|`End of life`|`GitHub-hosted`|
|`5.4`|`Stable`|`End of life`|`GitHub-hosted`|
|`5.5`|`Stable`|`End of life`|`GitHub-hosted`|
|`5.6`|`Stable`|`End of life`|`GitHub-hosted`, `self-hosted`|
|`7.0`|`Stable`|`End of life`|`GitHub-hosted`, `self-hosted`|
|`7.1`|`Stable`|`End of life`|`GitHub-hosted`, `self-hosted`|
|`7.2`|`Stable`|`End of life`|`GitHub-hosted`, `self-hosted`|
|`7.3`|`Stable`|`Security fixes only`|`GitHub-hosted`, `self-hosted`|
|`7.4`|`Stable`|`Active`|`GitHub-hosted`, `self-hosted`|
|`8.0`|`Stable`|`Active`|`GitHub-hosted`, `self-hosted`|
|`8.1`|`Nightly`|`In development`|`GitHub-hosted`, `self-hosted`|

**Notes:** 
- Specifying `8.1` in `php-version` input installs a nightly build of `PHP 8.1.0-dev`. See [nightly build setup](#nightly-build-setup) for more information.
- To use JIT on `PHP 8.0` and `PHP 8.1` refer to the [JIT configuration](#jit-configuration) section.

## :heavy_plus_sign: PHP Extension Support

PHP extensions can be setup using the `extensions` input. It accepts a `string` in csv-format.

- On `Ubuntu`, extensions which are available as a package or available on `PECL` can be setup.

```yaml
- name: Setup PHP with pecl extension
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    extensions: imagick, swoole
```

- On `Windows`, extensions available on `PECL` which have the `DLL` binary can be setup.

- On `macOS`, extensions available on `PECL` can be installed.

- Extensions installed along with PHP if specified are enabled.

- Specific versions of extensions available on `PECL` can be setup by suffixing the extension's name with the version. This is useful for installing old versions of extensions which support end of life PHP versions.

```yaml
- name: Setup PHP with specific version of PECL extension
  uses: shivammathur/setup-php@v2
  with:
    php-version: '5.4'
    tools: pecl
    extensions: swoole-1.9.3
```

- Pre-release versions extensions available on `PECL` can be setup by suffixing the extension's name with its state i.e `alpha`, `beta`, `devel` or `snapshot`.

```yaml
- name: Setup PHP with pre-release PECL extension
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    tools: pecl
    extensions: xdebug-beta
```

- Shared extensions can be removed by prefixing them with a `:`.

```yaml
- name: Setup PHP and remove shared extension
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'  
    extensions: :opcache
```

- Extension `intl` can be setup with specific `ICU` version for `PHP 5.6` to `PHP 7.4` in `Ubuntu` workflows by suffixing `intl` with the `ICU` version. `ICU 50.2` and newer versions are supported. Refer to [`ICU builds`](https://github.com/shivammathur/icu-intl#icu4c-builds) for the specific versions supported.

```yaml
- name: Setup PHP with intl
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    extensions: intl-67.1
```

- Extensions loaded by default after `setup-php` runs can be found on the [wiki](https://github.com/shivammathur/setup-php/wiki).

- These extensions have custom support:
  - `cubrid`, `pdo_cubrid` and `gearman` on `Ubuntu`.
  - `geos` on `Ubuntu` and `macOS`.
  - `blackfire`, `couchbase`, `ioncube`, `oci8`, `pdo_oci`, `phalcon3` and `phalcon4` on all supported OS.

- By default, extensions which cannot be added or removed gracefully leave an error message in the logs, the action is not interrupted. To change this behaviour you can set `fail-fast` flag to `true`. 

```yaml
- name: Setup PHP with fail-fast
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    extensions: oci8
  env:
    fail-fast: true
```

## :wrench: Tools Support

These tools can be setup globally using the `tools` input. It accepts a string in csv-format.

`behat`, `blackfire`, `blackfire-player`, `codeception`, `composer`, `composer-normalize`, `composer-prefetcher`, `composer-require-checker`, `composer-unused`, `cs2pr`, `deployer`, `flex`, `grpc_php_plugin`, `infection`, `pecl`, `phan`, `phing`, `phinx`, `phive`, `phpcbf`, `phpcpd`, `php-config`, `php-cs-fixer`, `phpcs`, `phpize`, `phpmd`, `phpspec`, `phpstan`, `phpunit`, `prestissimo`, `protoc`, `psalm`, `symfony`, `vapor-cli`

```yaml
- name: Setup PHP with tools
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    tools: php-cs-fixer, phpunit
```

- To set up a particular version of a tool, specify it in the form `tool:version`. The latest stable version of `composer` is set up by default. You can set up the required `composer` version by specifying `v1`, `v2`, `snapshot` or `preview` as versions or the exact version in semver format.

```yaml
- name: Setup PHP with composer v2
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    tools: composer:v2
```

- Tools `prestissimo` and `composer-prefetcher` will be skipped unless `composer:v1` is also specified in tools input. It is recommended to drop `prestissimo` and use `composer v2`.

- The latest versions of both agent `blackfire-agent` and client `blackfire` are setup when `blackfire` is specified in tools input. Please refer to the [official documentation](https://blackfire.io/docs/integrations/ci/github-actions "Blackfire.io documentation for GitHub Actions") for using `blackfire` with GitHub Actions.

- Version for other tools should be in `semver` format and a valid release of the tool. This is useful for installing tools for older versions of PHP. For example to set up `PHPUnit` on `PHP 7.2`.

```yaml
- name: Setup PHP with tools
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.2'
    tools: phpunit:8.5.8
```

- By default, tools which cannot be set up gracefully leave an error message in the logs, the action is not interrupted. To change this behaviour you can set `fail-fast` flag to `true`.

```yaml
- name: Setup PHP with fail-fast
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    tools: deployer
  env:
    fail-fast: true
```

**Notes**
- Input `tools` is useful to set up tools which you only use in GitHub Actions, thus keeping your `composer.json` tidy.
- If you do not want to use all your dev-dependencies in GitHub Actions workflow, you can run composer with `--no-dev` and install required tools using `tools` input to speed up your workflow.
- If you have a tool in your `composer.json`, do not setup it with `tools` input as the two instances of the tool might conflict.

## :signal_strength: Coverage Support

### Xdebug

Specify `coverage: xdebug` to use `Xdebug`.  
Runs on all [PHP versions supported](#tada-php-support "List of PHP versions supported on this GitHub Action").

```yaml
- name: Setup PHP with Xdebug
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    coverage: xdebug
```

### PCOV

Specify `coverage: pcov` to use `PCOV` and disable `Xdebug`.  
`PCOV` supports `PHP 7.1` and newer PHP versions.  
Tests with `PCOV` run much faster than with `Xdebug`.  
If your source code directory is other than `src`, `lib` or, `app`, specify `pcov.directory` using the `ini-values` input.  

```yaml
- name: Setup PHP with PCOV
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    ini-values: pcov.directory=api #optional, see above for usage.
    coverage: pcov
```

`PHPUnit` 8 and above supports `PCOV` out of the box.  
If you are using `PHPUnit` 5, 6 or 7, you will need `pcov/clobber`.  
Before executing your tests add the following step.

```yaml
- name: Setup PCOV
  run: |
    composer require pcov/clobber
    vendor/bin/pcov clobber
```

### Disable Coverage

Specify `coverage: none` to remove both `Xdebug` and `PCOV`.  
Consider disabling the coverage using this PHP action for these reasons.

- You are not generating coverage reports while testing.
- It will remove `Xdebug`, which will have a positive impact on PHP performance.
- You are using `phpdbg` for running your tests.
- You are profiling your code using `blackfire`.

```yaml
- name: Setup PHP with no coverage driver
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    coverage: none
```

  uses: actions/checkout@v2

- name: Setup PHP
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    extensions: mbstring, intl
    ini-values: post_max_size=256M, max_execution_time=180
    coverage: xdebug

```

### Matrix Setup

> Setup multiple PHP versions on multiple operating systems.

```yaml
jobs:
  run:
    runs-on: ${{ matrix.operating-system }}
    strategy:
      matrix:
        operating-system: ['ubuntu-latest', 'windows-latest', 'macos-latest']
        php-versions: ['7.3', '7.4']
        phpunit-versions: ['latest']
        include:
        - operating-system: 'ubuntu-latest'
          php-versions: '7.2'
          phpunit-versions: '8.5.13'    
    steps:
    - name: Checkout
      uses: actions/checkout@v2

    - name: Setup PHP
      uses: shivammathur/setup-php@v2
      with:
        php-version: ${{ matrix.php-versions }}
        extensions: mbstring, intl
        ini-values: post_max_size=256M, max_execution_time=180
        coverage: xdebug        
        tools: php-cs-fixer, phpunit:${{ matrix.phpunit-versions }}
```

### Nightly Build Setup

> Setup a nightly build of `PHP 8.1`. 

- This version is currently in development.
- `PECL` is installed by default with `PHP 8.1` on both `ubuntu` and `macOS`.
- Some user space extensions might not support this version currently.

```yaml
steps:
- name: Checkout
  uses: actions/checkout@v2

- name: Setup nightly PHP
  uses: shivammathur/setup-php@v2
  with:
    php-version: '8.1'
    extensions: mbstring
    ini-values: post_max_size=256M, max_execution_time=180
    coverage: xdebug
    tools: php-cs-fixer, phpunit
```

### Thread Safe Setup

> Setup `TS` or `NTS` PHP on `Windows`.

- `NTS` versions are setup by default.
- On `Ubuntu` and `macOS` only `NTS` versions are supported.
- On `Windows` both `TS` and `NTS` versions are supported.

```yaml
jobs:
  run:
    runs-on: windows-latest
    name: Setup PHP TS on Windows
    steps:
    - name: Checkout
      uses: actions/checkout@v2

    - name: Setup PHP
      uses: shivammathur/setup-php@v2
      with:
        php-version: '7.4'
      env:
        phpts: ts # specify ts or nts
```

### Force Update Setup

> Update to the latest patch of PHP versions.

- Pre-installed PHP versions on the GitHub Actions runner are not updated to their latest patch release by default.
- You can specify the `update` environment variable to `true` to force update to the latest release.

```yaml
- name: Setup PHP with latest versions
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
  env:
    update: true # specify true or false
```

### Verbose Setup

> Debug your workflow

To debug any issues, you can use the `verbose` tag instead of `v2`.

```yaml
- name: Setup PHP with logs
  uses: shivammathur/setup-php@verbose
  with:
    php-version: '7.4'
```

### Multi-Arch Setup

> Setup PHP on multiple architecture on Ubuntu GitHub Runners.

- `PHP 5.6` to `PHP 7.4` are supported by `setup-php` on multiple architecture on `Ubuntu`.
- For this, you can use `shivammathur/node` images as containers. These have compatible `Nodejs` and `spc` utility.
- Using `spc` you can run `setup-php` on both `i386` and `amd64` containers as opposed to [default syntax](#basic-setup), which only supports `amd64`.
- Currently, for `Arm` based setup, you will need [self-hosted runners](#self-hosted-setup).

```yaml
jobs:
  run:
    runs-on: ubuntu-latest
    container: shivammathur/node:latest-${{ matrix.arch }}
    strategy:
      matrix:
        arch: ["amd64", "i386"]
    steps:
      - name: Install PHP
        run: |
          # Update spc (See https://github.com/shivammathur/spc for options)
          spc -U

          # Install PHP
          spc --php-version "7.4" \
              --extensions "mbstring, intl" \
              --ini-values "post_max_size=256M, max_execution_time=180" \
              --coverage "xdebug" \
              --tools "php-cs-fixer, phpunit"
```

### Self Hosted Setup

> Setup PHP on a self-hosted runner.

- To set up a dockerized self-hosted runner, refer to this [guide](https://github.com/shivammathur/setup-php/wiki/Dockerized-self-hosted-runner-on-Ubuntu) to set up in an `Ubuntu` container and refer to this [guide](https://github.com/shivammathur/setup-php/wiki/Dockerized-self-hosted-runner-on-Windows) to set up in a `Windows` container.
- To set up the runner directly on the host OS or in a virtual machine, follow this [requirements guide](https://github.com/shivammathur/setup-php/wiki/Requirements-for-self-hosted-runners "Requirements guide for self-hosted runner to run setup-php") before setting up the self-hosted runner.
- If your workflow uses [services](https://help.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idservices "GitHub Actions Services"), then setup the runner on a Linux host or in a Linux virtual machine. GitHub Actions does not support nested virtualization on Linux, so services will not work in a dockerized container.

Specify the environment variable `runner` with the value `self-hosted`. Without this your workflow will fail.

```yaml
jobs:
  run:
    runs-on: self-hosted
    strategy:
      matrix:        
        php-versions: ['5.6', '7.0', '7.1', '7.2', '7.3', '7.4', '8.0']
    name: PHP ${{ matrix.php-versions }}
    steps:
    - name: Checkout
      uses: actions/checkout@v2

    - name: Setup PHP
      uses: shivammathur/setup-php@v2
      with:
        php-version: ${{ matrix.php-versions }}
      env:
        runner: self-hosted # Specify the runner.
```

**Notes**
- Do not setup multiple self-hosted runners on a single server instance as parallel workflow will conflict with each other.
- Do not setup self-hosted runners on the side on your development environment or your production server.
- Avoid using the same labels for your `self-hosted` runners which are used by `GitHub-hosted` runners.

### Local Testing Setup

> Test your `Ubuntu` workflow locally using [`nektos/act`](https://github.com/nektos/act "Project to test GitHub Actions locally").

```yaml
jobs:
  run:
    runs-on: ubuntu-latest
    name: PHP 7.4 Test
    steps:
    - name: Checkout
      uses: actions/checkout@v2

    - name: Setup PHP
      uses: shivammathur/setup-php@v2
      with:
        php-version: 7.4
```

Run the workflow locally with `act` using [`shivammathur/node`](https://github.com/shivammathur/node-docker "Docker image to run setup-php") docker images.

```bash
# For runs-on: ubuntu-latest
act -P ubuntu-latest=shivammathur/node:latest

# For runs-on: ubuntu-20.04
act -P ubuntu-20.04=shivammathur/node:focal

# For runs-on: ubuntu-18.04
act -P ubuntu-18.04=shivammathur/node:bionic

# For runs-on: ubuntu-16.04
act -P ubuntu-16.04=shivammathur/node:xenial
```

### JIT Configuration

> Enable Just-in-time(JIT) on PHP 8.0 and PHP 8.1.

- To enable JIT, enable `opcache` in cli mode by setting `opcache.enable_cli=1`.
- By default, `opcache.jit=1235` and `opcache.jit_buffer_size=256M` are set which can be changed using `ini-values` input.
- For detailed information about JIT related directives refer to the [`official PHP documentation`](https://www.php.net/manual/en/opcache.configuration.php#ini.opcache.jit "opcache.jit documentation").

For example to enable JIT in `tracing` mode with buffer size of `64 MB`. 

```yaml

### Cache Extensions

You can cache PHP extensions using `shivammathur/cache-extensions` and `action/cache` GitHub Actions. Extensions which take very long to set up when cached are available in the next workflow run and are enabled directly. This reduces the workflow execution time.  
Refer to [`shivammathur/cache-extensions`](https://github.com/shivammathur/cache-extensions "GitHub Action to cache php extensions") for details.

### Cache Composer Dependencies

If your project uses composer, you can persist the composer's internal cache directory. Dependencies cached are loaded directly instead of downloading them while installation. The files cached are available across check-runs and will reduce the workflow execution time.

```yaml
- name: Get composer cache directory
  id: composer-cache
  run: echo "::set-output name=dir::$(composer config cache-files-dir)"

- name: Cache dependencies
  uses: actions/cache@v2
  with:
    path: ${{ steps.composer-cache.outputs.dir }}
    key: ${{ runner.os }}-composer-${{ hashFiles('**/composer.lock') }}
    restore-keys: ${{ runner.os }}-composer-

- name: Install dependencies
  run: composer install --prefer-dist
```

**Notes**
- Please do not cache `vendor` directory using `action/cache` as that will have side effects.
- If you do not commit `composer.lock`, you can use the hash of `composer.json` as the key for your cache.
```yaml
key: ${{ runner.os }}-composer-${{ hashFiles('**/composer.json') }}
```

- If you support a range of `composer` dependencies and use `prefer-lowest` and `prefer-stable` options, you can store them in your matrix and add them to the keys.
```yaml
key: ${{ runner.os }}-composer-${{ hashFiles('**/composer.lock') }}-${{ matrix.prefer }}-
restore-keys: ${{ runner.os }}-composer-${{ matrix.prefer }}-
```

### Cache Node.js Dependencies

If your project has node.js dependencies, you can persist NPM or yarn cache directory. The cached files are available across check-runs and will reduce the workflow execution time.

```yaml
- name: Get node.js cache directory
  id: node-cache-dir
  run: echo "::set-output name=dir::$(npm config get cache)" # Use $(yarn cache dir) for yarn

- name: Cache dependencies
  uses: actions/cache@v2
  with:
    path: ${{ steps.node-cache-dir.outputs.dir }}
    key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }} # Use '**/yarn.lock' for yarn
    restore-keys: ${{ runner.os }}-node-
```

**Note:** Please do not cache `node_modules` directory as that will have side effects.

### Composer GitHub OAuth

If you have a number of workflows which setup multiple tools or have many composer dependencies, you might hit the GitHub's rate limit for composer. To avoid that you can add an `OAuth` token to the composer's config by setting `COMPOSER_TOKEN` environment variable. You can use [`GITHUB_TOKEN`](https://help.github.com/en/actions/configuring-and-managing-workflows/authenticating-with-the-github_token "GITHUB_TOKEN documentation") secret for this purpose.

```yaml
- name: Setup PHP
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
  env:
    COMPOSER_TOKEN: ${{ secrets.GITHUB_TOKEN }}
```

### Problem Matchers

Problem matchers are `json` configurations which identify errors and warnings in your logs and surface them prominently in the GitHub Actions UI by highlighting them and creating code annotations.

#### PHP

Setup problem matchers for your `PHP` output by adding this step after the `setup-php` step.

```yaml
- name: Setup problem matchers for PHP
  run: echo "::add-matcher::${{ runner.tool_cache }}/php.json"
```

#### PHPUnit

Setup problem matchers for your `PHPUnit` output by adding this step after the `setup-php` step.

```yaml
- name: Setup problem matchers for PHPUnit
  run: echo "::add-matcher::${{ runner.tool_cache }}/phpunit.json"
```

#### PHPStan

PHPStan supports error reporting in GitHub Actions, so it does not require problem matchers.

```yaml
- name: Setup PHP
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    tools: phpstan

- name: Run PHPStan
  run: phpstan analyse src
```

#### Psalm

Psalm supports error reporting in GitHub Actions with an output format `github`.

```yaml
- name: Setup PHP
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    tools: psalm

- name: Run Psalm
  run: psalm --output-format=github
```

#### Tools with checkstyle support

For tools that support `checkstyle` reporting like `phpstan`, `psalm`, `php-cs-fixer` and `phpcs` you can use `cs2pr` to annotate your code.  
For examples refer to [cs2pr documentation](https://github.com/staabm/annotate-pull-request-from-checkstyle).   

> Here is an example with `phpcs`.

```yaml
- name: Setup PHP
  uses: shivammathur/setup-php@v2
  with:
    php-version: '7.4'
    tools: cs2pr, phpcs

- name: Run phpcs
  run: phpcs -q --report=checkstyle src | cs2pr
```

## :bookmark: Versioning

- Use the `v2` tag as `setup-php` version. It is a rolling tag and is synced with the latest minor and patch releases. With `v2` you automatically get the bug fixes, new features and support for latest PHP releases. For debugging any issues `verbose` tag can be used temporarily. It outputs all the logs and is also synced with the latest releases.
- Semantic release versions can also be used. It is recommended to [use dependabot](https://docs.github.com/en/github/administering-a-repository/keeping-your-actions-up-to-date-with-github-dependabot "Setup Dependabot with GitHub Actions") with semantic versioning to keep the actions in your workflows up to date.
- Commit SHA can also be used, but are not recommended. They have to be updated with every release manually, without which you will not get any bug fixes or new features. 
- It is highly discouraged to use the `master` branch as version, it might break your workflow after major releases as they have breaking changes.
- If you are using the `v1` tag or a `1.x.y` version, you should [switch to v2](https://github.com/shivammathur/setup-php/wiki/Switch-to-v2 "Guide for switching from setup-php v1 to v2") as `v1` only gets critical bug fixes. Maintenance support for `v1` will be dropped with the last `PHP 8.0` release.
