Fork¶

Fork ( array $functions )

Sends every input value to every inner function. Output is the output of every inner function.

Parameters¶

functions: An array of Pipeline functions. If any of the elements in the array is an array it will be passed as argument to Compose, which is then used as the function.

Examples¶

Example #1¶

Basic usage example.

<?php
use Webbhuset\Pipeline\Constructor as F;

$fork = F::Fork([
    F::Map(function ($value) {
        return $value * 2;
    }),
    F::Map(function ($value) {
        return str_repeat('a', $value);
    }),
]);

$input = [1, 2, 3, 4, 5];

echo json_encode(iterator_to_array($fork($input)));

// Output: [2,"a",4,"aa",6,"aaa",8,"aaaa",10,"aaaaa"]
