In 2002, Yahoo selected PHP for Web site development and began to phase out its own proprietary server-side scripting language. Three years later, Michael Radwin reflects on how the switch to PHP offered both technical challenges and productivity increases.
The first part of the presentation offers a look inside Yahoo’s decision-making process to adopt an open-source scripting language. Radwin addresses why Yahoo selected PHP over other languages, focusing on the performance and stability required to serve billions of page views a day.
In the second part, Radwin discusses Yahoo’s PHP development methodology, which has enabled its engineers to rapidly implement features while still creating software that is maintainable over long periods of time.
