Practical Monads
Explore how practical monads such as IO, Reader, and others facilitate function chaining and side effect management in PHP. Understand monad functions and their role in maintaining purity and composability when handling IO operations and shared configuration.
We'll cover the following...
Overview
The Calculator type class, which is the focal point of this chapter, is only a microcosm of monad practicality. The reality is that the versatility of monads renders them convenient for solving generic problems. The most pervasive monads applicable to real-world problems are IO, State, Reader, List, and Writer monads. They have immense value in their innate generic qualities.
Monad functions
Monads provide specialized environments for function chaining or composition. Fundamentally, monads are specialized containers and are chainable. Functional programming languages, especially Haskell, provide their users with monad helper functions as built-in abstractions for programming aided by monads. ...
