Simple in-memory map/reduce for PHP iterables.

This library is for local data processing when you want a small, readable API and do not need distributed workers, external storage, or tuning knobs. It is the lighter counterpart to heavier MapReduce-style systems.

Why this exists
---------------

[](#why-this-exists)

- Works with any `iterable`, including arrays, generators, and custom iterators.
- Keeps all work inside one PHP process.
- Exposes a small fluent API that is easy to test.
- Lets you observe progress without coupling to a logger.

Install
-------

[](#install)

```
composer require jotaelesalinas/php-simple-mapreduce
