PHP Continuous Integration with GitHub Actions

Continuous Integration (CI) is a software development practice that involves automatically building, testing, and deploying code changes. GitHub Actions is a powerful tool for setting up CI workflows. In this guide, we'll explore how to create a PHP CI workflow with GitHub Actions and provide sample code.

1. Introduction to GitHub Actions

GitHub Actions is an integrated tool in GitHub that allows you to automate tasks and workflows. It is commonly used for CI/CD (Continuous Integration/Continuous Deployment) to ensure code quality and reliability.

2. Key Concepts and Techniques

2.1. Workflow Configuration

Create a YAML configuration file in your repository's

.github/workflows

2.2. Using PHP in GitHub Actions

Set up your workflow to use PHP for tasks like running tests, linting, or building your PHP application. You can use different PHP versions, depending on your project's requirements.

2.3. Running Tests

One common CI task is running tests for your PHP code. You can use PHPUnit or other testing frameworks. Ensure your workflow reports test results and code coverage.

2.4. Environment Variables

Use GitHub Actions secrets and environment variables to store sensitive information like API keys or database credentials securely.

3. Example: PHP CI Workflow with GitHub Actions

Here's a simplified example of a PHP CI workflow using GitHub Actions:

name: PHP Continuous Integration
on:
  push:
    branches:
      - main
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
uses: actions/checkout@v2
      - name: Set up PHP
uses: shivammathur/setup-php@v2
with:
  php-version: '8.0'
      - name: Install dependencies
run: composer install
      - name: Run tests
run: phpunit
      - name: Upload test coverage
uses: actions/upload-artifact@v2
with:
  name: coverage
  path: build/coverage
      - name: Deploy to staging (if tests pass)
if: success()
run: |
  # Add deployment steps here
    

4. Conclusion

Setting up PHP Continuous Integration with GitHub Actions is a valuable practice to ensure code quality and reliability. By automating testing and deployment, you can catch issues early in the development process and deliver better software.
