Continuous Integration for PHP Extensions

(Co-written with Alan Seiden)

CI/CDContinuous Integration (CI) ensures that every time a developer commits changes to a version control system such as Git, the code is automatically built and subjected to automated tests.

CI has been invaluable to us. As maintainers of PHP’s PDO_IBM and ibm_db2 extensions, we use CI to ensure high quality across platforms.

Platforms supported by PHP’s extensions for Db2 include IBM i, Unix/Linux, and Windows. While our focus is IBM i, we must ensure compatibility with the others. Reliance on manual testing would introduce the risk of broken builds or subtle bugs. Automation is a must.

In this post, we explain how we use CI principles when building and testing PHP’s Db2 extensions.
