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 or generators.

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

Features

Check out more detailed examples in the examples file.

This library includes common functions like

• map
• filter
• 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 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

Install with composer:

composer require escapio/php-iterables
