How can automated rollout of versions be achieved in PHP development?

Automated rollout of versions in PHP development can be achieved by using a continuous integration/continuous deployment (CI/CD) pipeline. This involves automating the process of building, testing, and deploying code changes to different environments. By setting up a CI/CD pipeline, developers can ensure that new versions are automatically rolled out without manual intervention.

// Sample PHP script for automated version rollout using a CI/CD pipeline

// Step 1: Build and test code changes
// This step can include running PHPUnit tests, code linting, and other automated tests

// Step 2: Deploy code changes to staging environment
// This can involve using tools like Jenkins, Travis CI, or GitLab CI to deploy changes to a staging server for further testing

// Step 3: Deploy code changes to production environment
// Once changes have been tested in the staging environment, they can be automatically deployed to the production server
