README

A powerful collection abstraction for the Beauty Framework.
Supports both eager and lazy data pipelines, multiple storage strategies, method chaining (map, filter, sortBy, paginate, etc.), strict interfaces, and full compatibility.

Features

Collection (eager)

• Fluent methods:
  • map, filter, where, sortBy, paginate, each, first, last, values
• Implements:
  • ArrayAccess, Countable, IteratorAggregate, JsonSerializable
• Smart last() optimization (iterator or buffered strategy)
• Storage strategies:
  • ArrayStorage (default)
  • DsMapStorage (if ext-ds is available)

LazyCollection

• Based on Generator
• Fluent methods:
  • map, filter, chunk, flatMap, reduce, take, first, toArray
• Memory efficient for large or infinite datasets

Interfaces

• CollectionInterface
• SupportsOperations
• SupportsAccessors
• LazyCollectionInterface

Installation

composer require beauty-framework/collection

Usage

Eager Collection

$collection = new Collection([
  ['name' => 'Kirill'],
  ['name' => 'Hui'],
  ['name' => 'Zver'],
]);

$filtered = $collection
    ->where('name', 'Kirill')
    ->map(fn($x) => strtoupper($x['name']))
    ->toArray();

Lazy Collection

$collection = new LazyCollection(fn() => yield from range(1, 1_000_000));

$result = $collection
    ->filter(fn($x) => $x % 2 === 0)
    ->take(5)
    ->flatMap(fn($x) => [$x, $x * 10])
    ->toArray();
