pipe

Description

Takes a set of functions and returns a new one that is the composition of those $fns. The result from the first function execution is piped in to the second function and so on.

It's usually used in combination with the apply function.

Parameters

fns

Functions to be piped.

Examples

Multiply 2 numbers and divide the result by two:

<?php

use function Lambdish\Phunctional\apply;
use function Lambdish\Phunctional\pipe;

$multiplier = function ($a, $b) {
    return $a * $b;
};

$byTwoDivider = function ($num) {
    return $num / 2;
};

$calculator = pipe($multiplier, $byTwoDivider);

apply($calculator, [20, 10]);
// => 15
