Piper is a pipe operator-first PHP utility library for array and string manipulation. It ports Laravel's collection and string utility methods to standalone functions.
It comes with array helpers:
use function Spatie\Piper\Arr\{filter, map};
$popular = $posts
|> filter(fn (Post $post) => $post->views > 1000)
|> map(fn (Post $post) => $post->title);
// ["Claude Talk Small. Code Still Big.", …]And string helpers:
use function Spatie\Piper\Str\{lower, replace};
'Hello, world!'
|> lower()
|> replace('world', 'Piper');
// "hello, Piper!"Since all functions work with primitives, you can mix and match:
use function Spatie\Piper\Arr\{filter, join, map, values};
use function Spatie\Piper\Str\{prefix, suffix};
[1, 2, 3, 4, 5, 6]
|> filter(fn (int $i) => $i % 2 === 0)
|> map(fn (int $i) => pow($i, 2))
|> values()
|> join(', ', ', and ')
|> prefix('The winning numbers are ')
|> suffix('.');
// "The winning numbers are 4, 16, and 36."You can install the package via composer:
