Build and test PHP apps

Azure Pipelines

You can create a pipeline that continuously builds, deploys, and tests your PHP projects.

To get instructions for deploying to Azure App Service on Linux with a pipeline, see Build and deploy to a PHP web app.

Create a pipeline

  1. Fork this GitHub repo:

  2. Sign in to your Azure DevOps organization and go to your project.

  3. Select PHP in the Configure tab.

  4. Examine your new pipeline. When you're ready, select Save and run.

    Save and run button in a new YAML pipeline

  5. You're prompted to commit a new azure-pipelines.yml file to your repository. Select Save and run again.

    If you want to watch your pipeline in action, select the build job.

    You now have a working YAML pipeline (azure-pipelines.yml) in your repository that's ready for you to customize!

When you want to make changes to your pipeline, select your pipeline on the Pipelines page, and then Edit the azure-pipelines.yml file.

Read further to learn some of the more common ways to customize your pipeline.

Build environment

Use Azure Pipelines to build your PHP projects without requiring setup of infrastructure. PHP is preinstalled on Microsoft-hosted agents in Azure Pipelines, along with many common libraries per PHP version. You can use Linux, macOS, or Windows agents to run your builds.

For more information and the exact versions of PHP that get preinstalled, see Microsoft-hosted agents.

Use a specific PHP version

On the Microsoft-hosted Ubuntu agent, multiple versions of PHP are installed. A symlink at /usr/bin/php points to the currently set PHP version, so that when you run php, the set version executes.

To use a PHP version other than the default, the symlink can be pointed to that version using the update-alternatives tool. Set the PHP version that you want by adding the following snippet to your azure-pipelines.yml file and change the value of the phpVersion variable.

  vmImage: 'ubuntu-latest'

  phpVersion: 7.2

- script: |
    sudo update-alternatives --set php /usr/bin/php$(phpVersion)
    sudo update-alternatives --set phar /usr/bin/phar$(phpVersion)
    sudo update-alternatives --set phpdbg /usr/bin/phpdbg$(phpVersion)
    sudo update-alternatives --set php-cgi /usr/bin/php-cgi$(phpVersion)
    sudo update-alternatives --set phar.phar /usr/bin/phar.phar$(phpVersion)
    php -version
  displayName: 'Use PHP version $(phpVersion)'

Install dependencies

To use Composer to install dependencies, add the following snippet to your azure-pipelines.yml file.

- script: composer install --no-interaction --prefer-dist
  displayName: 'composer install'

Test with phpunit

To run tests with phpunit, add the following snippet to your azure-pipelines.yml file.

- script: ./phpunit
  displayName: 'Run tests with phpunit'

Retain the PHP app with the build record

To save the artifacts of this build with the build record, add the following snippet to your azure-pipelines.yml file. Optionally, customize the value of rootFolderOrFile to alter what is included in the archive.

- task: ArchiveFiles@2
    rootFolderOrFile: '$(system.defaultWorkingDirectory)'
    includeRootFolder: false
- task: PublishBuildArtifacts@1

Using a custom composer location

If your composer.json is in a subfolder instead of the root directory, you can use the --working-dir argument to tell composer what directory to use. For example, if your composer.json is inside the subfolder pkgs

composer install --no-interaction --working-dir=pkgs

You can also specify the absolute path, using the built-in system variables:

composer install --no-interaction --working-dir='$(system.defaultWorkingDirectory)/pkgs'

Next steps

For your PHP app, you can also build an image and push it to a container registry.
