README

This library implements common data collections and containers in PHP.

Install

It can be installed in whichever way you prefer, but we recommend Composer.

$ composer require graze/data-structure

Usage

<?php

use Graze\DataStructure\Collection\Collection;
use Graze\DataStructure\Container\Container;
use Graze\DataStructure\Container\FlatContainer;

// Collection
$collection = new Collection(['foo', 'bar']);
$collection->add('baz');
$collection->contains('baz');
$collection->getAll();
$collection->filter(function ($item) {});
$collection->map(function ($item) {});
$collection->reduce(function ($res, $item) {});
$collection->sort(function ($itemA, $itemB) {});
$collection->sortOn(function ($item) {});

// Container
$container = new Container(['foo' => 0, 'bar' => 1]);
$container->add('baz', 2);
$container->has('baz');
$container->forAll(function ($value, $key) {});
$container->get('baz');
$container->set('bam', 3);
$container->remove('bam');

// FlatContainer
$container = new FlatContainer(['foo' => 0, 'bar' => ['child' => 'arr'], 'baz' => new Container(['ack' => 'bar'])]);
$container->has('bar.child');
$container->has('baz.ack');
$container->get('bar.child');
$container->get('baz.ack');
$container->set('bar.other', 'more');
$container->remove('baz.ack');

Immutable structures

<?php

use Graze\DataStructure\Collection\ImmutableCollection;
use Graze\DataStructure\Container\ImmutableContainer;
use Graze\DataStructure\Container\ImmutableFlatContainer;

// Immutable collection
$collection = new ImmutableCollection(['foo', 'bar']);
$collection = $collection->add('baz');
$collection = $collection->filter(function ($item) {});
$collection = $collection->sort(function ($itemA, $itemB) {});
$collection = $collection->sortOn(function ($item) {});

// Immutable container
$container = new ImmutableContainer(['foo' => 0, 'bar' => 1]);
$container = $container->add('baz', 2);
$container = $container->set('bam', 3);
$container = $container->remove('bam');

// Immutable flat container
$container = new ImmutableFlatContainer(['foo' => 0, 'bar' => ['child' => 'arr'], 'baz' => new ImmutableContainer(['ack' => 'bar'])]);
$container = $container->add('a.new.array', 'more');
$container = $container->set('bar.other', 'more');
$container = $container->remove('baz.ack');
