PHP 8.5 brought us the pipe operator. PHP 8.6 will bring us the rest of the picture: Partial function application and (hopefully) a compose operator. Together, these seemingly minor features revolutionize how we can write and structure code.

So what does that look like? What do these new language features do, and how can they help us write better, more compact, more understandable, more testable code? Is the era of functional programming in PHP finally here?

In this session we'll review these and related functionality that are quietly ushering in revolution in how PHP can be written, and why the future looks so bright.
