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."
```
