Join me on an exciting journey through 30 years of PHP and 25 years of PHPUnit! As the creator of PHPUnit and a member of The PHP Foundation’s board, I’ll dive into the fascinating history of PHP and PHPUnit. Discover how these two giants have shaped the web development landscape, from PHP’s humble beginnings to PHPUnit’s evolution into a testing powerhouse.
Get ready for insights, anecdotes, and a look at what the future holds for PHP and its ecosystem. Let’s celebrate three decades of Open Source innovation and collaboration!
I most recently presented “30 Years of Code, 25 Years of Tests: A Journey Through Code and Community” at the International PHP Conference on October 29, 2025 in Munich.

About me
My name is Sebastian Bergmann, and I have been working as a software developer and consultant in the PHP ecosystem for over 25 years. I support development teams in creating better software through modern practices, tools and training.
I am deeply committed to Open Source, maintain critical Open Source projects in the PHP ecosystem, and help shape the work of the PHP Foundation as a member of its board. I have also represented the interests of Open Source at the European Commission and am active in the Open Source Working Group (“Arbeitskreis Open Source Software”) of the German Informatics Society (“Gesellschaft für Informatik”).
I live and breathe Open Source and help shape how developers around the world test, write, and maintain their code.

This presentation is part of a series in which I use my personal and professional development as an example to reflect on changes in software development over the last few decades.
“Von AmigaBASIC bis KI”, “25 Jahre Open Source”, and “30 Years of Code, 25 Years of Tests” recollect both my individual journey as a developer and the transformation of the programming landscape: from the early beginnings with AmigaBASIC to my Open Source involvement and a look back at 30 years of PHP and 25 years of PHPUnit. The focus is on technical and procedural changes in software development.
