Modern PHP, Standards, and Community (phpDay 2017)

Learn how to structure and maintain a modern day PHP project using the latest standards. We'll walk through recent language improvements and how they will affect your day to day development. This will use code examples to give you in depth, real world examples of usage.

We'll also cover the latest community initiatives and standards including the PHPFIG along with the PSRs they have introduced.
