🚀 Quick Start

Array Utilities

use Kit\Utils\Arr;

// Add an element
$array = Arr::add(['a' => 1], 'b', 2);
// ['a' => 1, 'b' => 2]

// Get an element
$value = Arr::get(['a' => 1, 'b' => 2], 'a'); // 1
$default = Arr::get(['a' => 1], 'c', 'default'); // 'default'

// Take first N elements
$first = Arr::take([1, 2, 3, 4, 5], 3); // [1, 2, 3]

// Get element by index
$nth = Arr::nth([10, 20, 30], 1); // 20

// Drop elements
$dropped = Arr::drop([1, 2, 3], 1); // [2, 3]

// Remove falsey elements
$compact = Arr::compact([0, '', false, 'hello', null]); // ['hello']

// Remove specific element
$except = Arr::except(['a' => 1, 'b' => 2], 'a'); // ['b' => 2]

// First and last element
$first = Arr::first([1, 2, 3]); // 1
$last = Arr::last([1, 2, 3]); // 3

// Filter by keys
$only = Arr::only(['a' => 1, 'b' => 2, 'c' => 3], ['a', 'c']); // ['a' => 1, 'c' => 3]

// Fill array
$filled = Arr::fill([1, 2, 3], 'x'); // ['x', 'x', 'x']

// Sort array
$sorted = Arr::sort([3, 1, 4, 1, 5]); // [1, 1, 3, 4, 5]

// Remove duplicates
$unique = Arr::unique([1, 2, 2, 3, 3, 3]); // [1, 2, 3]

// Concatenate arrays
$concatenated = Arr::concat([1, 2], [3, 4]); // [1, 2, 3, 4]

// Get random element
$random = Arr::random([1, 2, 3, 4, 5]); // random element

String Utilities

use Kit\Utils\Str;

// Convert to uppercase
$upper = Str::upper('hello'); // 'HELLO'

// Convert to lowercase
$lower = Str::lower('HELLO'); // 'hello'

// Convert to title case
$title = Str::title('hello world'); // 'Hello World'

// Capitalize first character
$capitalize = Str::capitalize('hello'); // 'Hello'

// Check if string contains substring
$contains = Str::contains('hello world', 'world'); // true

// Check if string starts with substring
$starts = Str::startsWith('hello world', 'hello'); // true

// Check if string ends with substring
$ends = Str::endsWith('hello world', 'world'); // true

// Replace substring
$replace = Str::replace('hello world', 'world', 'php'); // 'hello php'

// Split string
$split = Str::split('a,b,c', ','); // ['a', 'b', 'c']

// Trim whitespace
$trim = Str::trim('  hello  '); // 'hello'

// Repeat string
$repeat = Str::repeat('ha', 3); // 'hahaha'

// Limit string length
$limit = Str::limit('hello world', 5); // 'hello...'

// Convert to slug
$slug = Str::slug('My Awesome Post'); // 'my-awesome-post'

// Count characters
$count = Str::count('hello'); // 5

// Base64 encoding
$encoded = Str::base64Encode('hello'); // 'aGVsbG8='
$decoded = Str::base64Decode('aGVsbG8='); // 'hello'

// HTML escape
$escaped = Str::htmlEscape('<script>'); // '&lt;script&gt;'

// HTML unescape
$unescaped = Str::htmlUnescape('&lt;script&gt;'); // '<script>'

File Utilities

use Kit\Utils\Fs\File;

// Save file
$saved = File::save('path/to/file.txt', 'File content');

// Read file
$content = File::get('path/to/file.txt');

// Check if file exists
$exists = File::has('path/to/file.txt'); // true/false

Data Structures

Stack (LIFO - Last In First Out)

use Kit\Container\Stack;

$stack = new Stack();

// Push element
$stack->push('first');
$stack->push('second');
$stack->push('third');

// Pop element
$item = $stack->pop(); // 'third'

// Convert to array
$array = $stack->toArray(); // ['first', 'second']

HashTable

use Kit\Container\HashTable;

$table = new HashTable();

// Set value
$table->set('user_1', 'John Doe');
$table->set('user_2', 'Jane Doe');

// Get value
$value = $table->get('user_1'); // 'John Doe'

// Check if key exists
$exists = $table->has('user_1'); // true

// Convert to array
$all = $table->toArray();

Tree

use Kit\Entity\Tree;

$root = new Tree('Root');
$child = new Tree('Child');

// Access value
echo $root->value; // 'Root'

Graph

use Kit\Contracts\Interfaces\Graph;

$graph = new Graph();

// Add nodes
$node1 = $graph->addNode('Node1');
$node2 = $graph->addNode('Node2');

// Add edge
$graph->addEdge($node1, $node2);

// Get node
$node = $graph->getNode('Node1');

💡 Practical Examples

Real-world Data Processing

use Kit\Utils\Arr;
use Kit\Utils\Str;

// Sample user data
$users = [
    ['id' => 1, 'name' => 'John', 'email' => 'john@example.com', 'status' => 'active'],
    ['id' => 2, 'name' => 'Jane', 'email' => 'jane@example.com', 'status' => 'inactive'],
    ['id' => 3, 'name' => 'Bob', 'email' => 'bob@example.com', 'status' => 'active'],
];

// Get only active users
$active = array_filter($users, fn($user) => $user['status'] === 'active');

// Extract emails
$emails = array_map(fn($user) => $user['email'], $users);

// Extract specific fields
$ids = Arr::column($users, 'id'); // [1, 2, 3]

Input Data Cleaning

use Kit\Utils\Str;
use Kit\Utils\Arr;

$input = [
    'name' => '  John Doe  ',
    'email' => 'JOHN@EXAMPLE.COM',
    'description' => '',
    'website' => null,
];

// Clean input
$input['name'] = Str::trim($input['name']);
$input['email'] = Str::lower($input['email']);

// Remove empty values
$clean = Arr::compact($input);

// Result: ['name' => 'John Doe', 'email' => 'john@example.com']

Working with URLs and Slugs

use Kit\Utils\Str;

$title = 'How to Build a PHP Application';

// Create URL-friendly slug
$slug = Str::slug($title); // 'how-to-build-a-php-application'

// Create filename
$filename = $slug . '.md'; // 'how-to-build-a-php-application.md'

// Check URL patterns
$isValid = Str::startsWith('https://example.com/api', 'https://');

Working with Configuration

use Kit\Utils\Arr;

$config = [
    'app' => ['name' => 'MyApp', 'version' => '1.0'],
    'db' => ['host' => 'localhost', 'port' => 3306],
    'cache' => ['driver' => 'redis'],
];

// Get specific values
$appName = Arr::get($config, 'app'); // Using array keys
$dbHost = Arr::get($config, 'db');

// Add new config
$newConfig = Arr::add($config, 'queue', ['driver' => 'redis']);

// Get only app config
$appConfig = Arr::only($config['app'], ['name', 'version']);

File Operations

use Kit\Utils\Fs\File;

// Save configuration
$config = ['app' => 'MyApp', 'debug' => true];
File::save('config.json', json_encode($config));

// Read configuration
if (File::has('config.json')) {
    $content = File::get('config.json');
    $config = json_decode($content, true);
}

// Create backup
$original = File::get('data.txt');
File::save('data.backup.txt', $original);

Using Data Structures

use Kit\Container\Stack;
use Kit\Container\HashTable;

// Undo/Redo functionality with Stack
$stack = new Stack();
$stack->push('action1');
$stack->push('action2');
$stack->push('action3');

$lastAction = $stack->pop(); // 'action3'

// Cache with HashTable
$cache = new HashTable();
$cache->set('user:1', ['name' => 'John', 'email' => 'john@example.com']);
$cache->set('user:2', ['name' => 'Jane', 'email' => 'jane@example.com']);

$user = $cache->get('user:1');
$hasUser = $cache->has('user:1'); // true
