Escapio PHP-Iterables
=====================

[](#escapio-php-iterables)

Description
-----------

[](#description)

PHP-Iterables is a simple utility library for PHP to provide an easy and consistent way of using iterables, no matter which type of iterable you work on: arrays, [iterators](https://www.php.net/manual/en/class.iterator.php)or [generators](https://www.php.net/manual/en/class.generator.php).

Furthermore, it allows you to chain several iterator functions in a fluent, easier-to-read way.

Features
--------

[](#features)

Check out more detailed examples in the [examples](examples.md) file.

This library includes common functions like

- [map](examples.md#map)
- [filter](examples.md#filter)
- [reduce](examples.md#reduce)

```
$double_iterable = map($iterable_of_numbers, fn($number) => $number * 2);
```

```
$filtered_iterable = filter($iterable_of_numbers, fn($number) => $number < 5);
```

```
$iterable = function () {
    yield 1;
    yield 2;
}
toArray($iterable); // [1, 2]
```

The [iterable-Builder](examples.md#builder) allow you to combine these functions in a fluent syntax:

```
(new \Escapio\Iterables\Builder())
  ->from(['Alice', 'Bob', 'Chuck'])
  ->map(strtolower(...))
  ->filter(fn ($name) => $name !== 'chuck')
  ->loop(function ($name) {
    echo $name . PHP_EOL;
  });
  // "alice"
  // "bob"
```

Installation
------------
