Sebastian Bergmann | The Online PHP Conference |

PHP has evolved a lot since its original release a quarter century ago, both with regards to the language's syntax and semantics as well as its interpreter's runtime characteristics. Especially the type system has been improved considerably. But how do compilers, IDEs, and tools benefit from more type information in the code?

This presentation provides well-founded answers to these and other questions about PHP 8's type system and you will learn how to develop robust software with PHP.
