README

A PHP class for fast iterables manipulation (arrays, generators, iterators).

All predicate / mutator callables receive the current value, current key and the whole collection as arguments.

map & filter do not execute immediately, but instead stack up until you need to get a value (calling squash, toArray, value). Where possible helpers use map & filter in order to minimize RAM usage. This means that it is possible to iterate through a large file reading line by line while maintaining a minimal memory footprint.

Install

Via Composer

composer require vakata/collection

Usage

$collection = \vakata\collection\Collection::from([1,2,3,4,5,6]);
$result = $collection
    ->filter(function ($v) { return $v % 2 === 0; })
    ->map(function ($v) { return $v + 1; })
    ->head(2)
    ->toArray();
