README

This library contains functional utilities intended for use with PHP 8.4 and later. Its primary tool is the pipe() function, which takes a starting argument and then a series of callables to "pipe" that argument through. Most other functions are utilities that produce a closure that takes the return from a previous pipe() step as its only argument.

Requirements

Requires PHP 8.4+

Installation

composer require cline/fp
