Usage

The most simple pipeline is just a sequence of steps where the output is handed to the next step and eventually returned out of the bottom:

<?php

use Solution10\Pipeline\Pipeline;

$w = (new Pipeline())
    ->step('double', function ($input) {
        return $input * 2;
    })
    ->step('add-one', function ($input) {
        return $input + 1;
    })
    ->step('stringify', function ($input) {
        return 'Result: '.$input;
    })
;

$result = $w->run(2);
// $result is "Result: 5"

Each step is given a name as the first parameter and a callable as it's second.

Pipeline::run() is then called with the input to generate the output.

There are various types of run() you can do, as well as variety of ways of defining steps, see the Userguide for more details.
