PHP Array Indexer
=================

[](#php-array-indexer)

Tiny PHP functions for indexing and grouping arrays and iterables by custom keys.

The package is intentionally small:

- no framework dependency;
- no service container;
- no classes required;
- works with arrays, objects, Doctrine entities, DTOs, generators and any iterable.

Useful when you receive a list of objects from a database and want fast access by `id`, `uuid`, `slug`, `email`, `externalId`, or any other calculated key.
