Functional programming is a paradigm that emphasizes expressing program logic as compositions of pure functions. PHP is a good fit for functional programming as functions are first-class citizens in its userland.
 
This course introduces you to the core concepts of functional programming, like pure functions, immutable data structures, and referential transparency. From there, you'll explore ways to handle errors with default values and callbacks while also exploring sum types such as Either or Maybe. Next, you'll look at functors before diving deep into monads, including IO, State, Reader, and List.
 
By the end of this course, you'll have a keen understanding of how to apply these principles in practice through a worked-out project. Not only will you know another way to program, but you’ll also feel confident enough to apply these ideas to your projects in PHP.

Learn Functional Programming in PHP

* Functional programming is a cognitive load-reducing paradigm based on the use of pure functions. It has a place in PHP’s vast ecosystem.

* Functional programming is a long-standing programming approach that emphasizes the use of expressions to architect computer programs.

* Functional programming has found its way into scripting languages like PHP, JavaScript, Ruby, and Python. In doing so, it has become viable outside of academia.

* PHP offers a multiparadigm runtime with first-class functions.
