Debugging Our Way Through PHP

In this presentation, we are going to have a look at the journey that PHP has made with the PHP 7 and PHP 8 releases, by using the latest Xdebug to see what actually goes on. We're literally going to debug our way out of PHP's new features! Join me to have a look at how the type system is strengthened with Enumerations and "never", Fibers, a new closure syntax, the First Class Callable Syntax, intersection types, and other new smaller features, as well as a preview of what PHP 8.3 and Xdebug 3.3 are going to bring.
