In December 2015, PHP 7.0 was released marking a new milestone for PHP and web application developers. We thought all was going to be easy to migrate to PHP 7.0. Unfortunately, many extensions and tools we use weren’t ready yet. In December 2016 PHP 7.1 was released, and the urgency to update became real as PHP 5.6 was nearing end-of-life. In this talk, I describe the analysis and the challenges we faced migrating towards PHP 7.1 so you can learn how to defeat those challenges if you plan to migrate too.

Thank you for talking about how important it is to keep our codebases clean (especially removing non-critical dependencies) and to keep up to date as new versions of PHP come around.

Crucial topic, and the speaker was great.

A great counter-point to Sebastian's talk.
This talk gives us a real idea about what to expect as we upgrade, warts and all.
