Functional programming utilities for PHP.
This library extensively uses curried functions and the pipe combinator.
If you don't like the following code:
self::someMethod(
array_filter(
array_map(
fn ($i) => $i + 1,
[1, 2, 3],
),
fn ($i) => $i % 2 === 0,
);
);Or:
self::someMethod(
ArrayList::fromIterable([/*...*/]),
->map(fn ($i) => $i + 1),
->filter(fn ($i) => $i % 2 === 0),
);Then this library might interest you:
<?php
declare(strict_types=1);
use Fp4\PHP\ArrayList as l;
use function Fp4\PHP\Combinator\pipe;
final class App
{
/**
* @param list<int> $list
* @return list<string>
*/
public function run(array $list): array
{
return pipe(
$list,
l\map(fn($i) => $i + 1),
l\filter(fn($i) => 0 === $i % 2),
self::toString(...),
);
}
/**
* @param list<int> $list
* @return list<string>
*/
public static function toString(array $list): array
{
return pipe(
$list,
l\map(fn($i) => (string)$i),
);
}
