PHP Iter Tools

• 1. Usage

Simple PHP library for making working with iterators more fun.

Heavily inspired by rust’s iterators.

Currently not all methods are implemented, but the most important ones are. Use with caution.

1. Usage

$iterator = new ArrayIterator([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]);
$iterator = $iterator
    ->filter(fn ($value) => $value % 2 === 0)
    ->map(fn ($value) => $value * 2)
    ->take(4);

assert($iterator->collect() === [4, 8, 12, 16]);
