ArrayKit

ArrayKit is a modern PHP 8.2+ library offering powerful array manipulation utilities, dynamic configuration management, and hookable “get/set” functionality.
It’s designed to handle everything from simple, single-dimensional arrays to deeply nested or multidimensional data structures. It also provides a flexible config system and advanced hooking for data transformation.

Features

• Single-Dimensional Array Helpers (ArraySingle):
  • Check if an array is associative or a list.
  • Filter, paginate, detect duplicates, compute averages, etc.
• Multi-Dimensional Array Helpers (ArrayMulti):
  • Flatten or collapse arrays, measure nesting depth, sort recursively, filter by custom conditions.
• Dot Notation Utilities (DotNotation):
  • Flatten/expand arrays using “dot” keys (e.g. user.profile.name).
  • Get, set, or remove nested values via a simple dotted key system.
• Config System (Config, DynamicConfig):
  • Centralized loading, retrieving, and setting of configuration values (via dot notation).
  • Optional hooking on get/set for dynamic transformations (DynamicConfig).
• Hooking / On-Get/On-Set (HookTrait):
  • Attach callable hooks to specific keys to transform data at runtime.
  • E.g., automatically hash passwords on set, or format strings on get.
• Collection Classes (BucketCollection, HookedCollection):
  • Provides an OOP wrapper around arrays, implementing ArrayAccess, Iterator, Countable, and JsonSerializable.
  • The HookedCollection extends this with hooks for on-get/on-set transformations.

Requirements

• PHP 8.2 or above

Installation

composer require infocyph/arraykit

Quick Usage Examples

1. Single-Dimensional Array Helpers

use Infocyph\ArrayKit\Array\ArraySingle;

$array = [1, 2, 3, 2];

// Check if the array is a list
$isList = ArraySingle::isList($array); // true

// Get duplicates
$duplicates = ArraySingle::duplicates($array); // [2]

// Paginate
$pageData = ArraySingle::paginate($array, page:1, perPage:2); // [1, 2]

2. Multi-Dimensional Array Helpers

use Infocyph\ArrayKit\Array\ArrayMulti;

$arr = [
    [1, 2],
    [3, 4, [5, 6]],
];

// Flatten the entire array to a single level
$flattened = ArrayMulti::flatten($arr);
// [1, 2, 3, 4, 5, 6]

// Collapse one level (concatenate sub-arrays)
$collapsed = ArrayMulti::collapse($arr);
// [1, 2, 3, 4, [5, 6]]

// Measure nesting depth
$depth = ArrayMulti::depth($arr);
// 3 (since there's a nested level [5, 6])

// Sort recursively (ascending by default)
$sorted = ArrayMulti::sortRecursive($arr);
// After sorting each nested sub-array

3. Dot Notation

use Infocyph\ArrayKit\Array\DotNotation;

$data = [
    'user' => [
        'profile' => [
            'name' => 'Alice'
        ]
    ]
];

// Get using dot notation
$name = DotNotation::get($data, 'user.profile.name'); // "Alice"

// Set using dot notation
DotNotation::set($data, 'user.profile.email', 'alice@example.com');

// Flatten
$flat = DotNotation::flatten($data);
// [ 'user.profile.name' => 'Alice', 'user.profile.email' => 'alice@example.com' ]

4. Dynamic Config with Hooks

use Infocyph\ArrayKit\Config\DynamicConfig;

// Suppose you have a DynamicConfig instance:
$config = new DynamicConfig();

// Load from a PHP file returning an array
$config->loadFile('/path/to/config.php');

// Attach a hook that runs whenever we set "db.password"
$config->onSet('db.password', function ($value) {
    return password_hash($value, PASSWORD_BCRYPT);
});

// Setting db.password automatically hashes it:
$config->set('db.password', 'secret123');

// Getting "db.password" will run any "on get" hooks if set.
// (By default, there's none unless you attach it.)
$hashedPassword = $config->get('db.password');

5. Hooked Collection

use Infocyph\ArrayKit\Functional\HookedCollection;

$hooked = new HookedCollection(['name' => 'Alice']);

// On-get hook: force uppercase
$hooked->onGet('name', fn($val) => strtoupper($val));

// On-set hook: add a prefix
$hooked->onSet('title', fn($val) => 'Title: '.$val);

// Getting 'name' triggers the on-get hook
echo $hooked['name']; 
// Outputs: "ALICE"

// Setting 'title' triggers the on-set hook
$hooked['title'] = 'Admin'; 
echo $hooked['title']; 
// Outputs: "Title: Admin"
