📝 Usage

Use this GitHub Action when the extensions you are adding in setup-php are installed and take a long time to set up. If you are using extensions which have the result Installed and enabled in the logs like pecl extensions on Ubuntu or extensions which have custom support, it is recommended to use this action to cache your extensions.


php-version (required)

  • Specify the PHP version you want to set up.
  • Accepts a string. For example '8.1'.
  • Accepts latest to set up the latest stable PHP version.
  • Accepts nightly to set up a nightly build from the master branch of PHP.
  • Accepts the format d.x, where d is the major version. For example 5.x, 7.x and 8.x.
  • See PHP support for supported PHP versions.

extensions (required)

  • Specify the extensions you want to set up.
  • Accepts a string in csv-format. For example mbstring, xdebug, :opcache.
  • Extensions prefixed with : are ignored in output cache key.

key (required)

  • Specify the key to identify the cache version.
  • Accepts any string. For example cache-v1.
  • Changing this would reset the cache.

See action.yml and usage below for more info.


Cache extensions in a PHP workflow

    runs-on: ${{ matrix.operating-system }}
        operating-system: [ubuntu-latest, windows-latest, macos-latest]
        php-versions: ['7.4', '8.0', '8.1']
    name: PHP ${{ matrix.php-versions }} Test on ${{ matrix.operating-system }}
      extensions: intl, pcov
      key: cache-v1 # can be any string, change to clear the extension cache.
    - name: Checkout
      uses: actions/checkout@v3

    - name: Setup cache environment
      id: extcache
      uses: shivammathur/cache-extensions@v1
        php-version: ${{ matrix.php-versions }}
        extensions: ${{ env.extensions }}
        key: ${{ env.key }}

    - name: Cache extensions
      uses: actions/cache@v2
        path: ${{ steps.extcache.outputs.dir }}
        key: ${{ steps.extcache.outputs.key }}
        restore-keys: ${{ steps.extcache.outputs.key }}

    - name: Setup PHP
      uses: shivammathur/setup-php@v2
        php-version: ${{ matrix.php-versions }}
        extensions: ${{ env.extensions }}

Thread Safe Setup

If you set up both TS and NTS PHP versions on Windows in your workflow, please add ${{ env.phpts }} to key and restore-keys inputs in actions/cache step in the above workflow to avoid a conflicting cache.

- name: Cache extensions
  uses: actions/cache@v2
    path: ${{ steps.extcache.outputs.dir }}
    key: ${{ steps.extcache.outputs.key }}-${{ env.phpts }}
    restore-keys: ${{ steps.extcache.outputs.key }}-${{ env.phpts }}
