• ✨ Text & Placeholder Utilities — TextFormatter, PlaceholderRenderer, RegexHelper, SecureCompare Powerful text formatting, placeholder rendering, and secure string comparison tools.

• 🕒 Date & Time Utilities — DateFormatter, DateHelper Humanized difference, timezone conversion, and localized date rendering (EN/AR/FR).

• 🧩 Validation & Filtering Tools — Validator, Filter, ArrayHelper Email/URL/UUID/Slug validation, input detection, and advanced array cleanup utilities.

• ⚙️ Enums & Constants Standardization — TextDirectionEnum, MessageTypeEnum, ErrorCodeEnum, PlatformEnum, AppEnvironmentEnum, CommonPaths, CommonLimits, CommonHeaders, Defaults, EnumHelper Centralized enum and constant definitions ensuring consistent standards, reusable helpers, and unified configuration across all Maatify libraries.

---

⚠️ Design Scope Notice

maatify/common is intentionally limited to pure helpers, DTOs, traits, enums, and shared utilities.

It contains no adapters, repositories, drivers, storage contracts, or IO-related abstractions. Any such responsibilities belong to dedicated infrastructure packages.

⚙️ Installation

composer require maatify/common

---

📦 Dependencies

This library directly relies on:

Dependency	Purpose	Link
ezyang/htmlpurifier	Secure HTML/XSS sanitization engine	github.com/ezyang/htmlpurifier
psr/log	Standardized PSR-3 logging interface	www.php-fig.org/psr/psr-3
phpunit/phpunit	Unit testing framework (development only)	phpunit.de

maatify/common integrates these open-source libraries to deliver a consistent and secure foundation for all other Maatify components.

🧠 Note: maatify/common automatically configures HTMLPurifier to use an internal cache directory at storage/purifier_cache for optimized performance. This ensures faster sanitization on subsequent calls without requiring manual setup.

If you wish to override the cache path, set the environment variable:

HTMLPURIFIER_CACHE_PATH=/path/to/custom/cache

or modify it programmatically via:

$config->set('Cache.SerializerPath', '/custom/cache/path');

---

🧠 SingletonTrait

A clean, PSR-friendly Singleton implementation to manage single-instance service classes safely.

🔹 Example Usage

use Maatify\Common\Traits\SingletonTrait;

final class ConfigManager
{
    use SingletonTrait;

    public function get(string $key): ?string
    {
        return $_ENV[$key] ?? null;
    }
}

// ✅ Always returns the same instance
$config = ConfigManager::obj();

// ♻️ Reset (for testing)
ConfigManager::reset();

✅ Features

• Prevents direct construction, cloning, and unserialization.
• Provides static obj() to access the global instance.
• Includes reset() for testing or reinitialization.

---

📚 Example Usage

🔹 Paginate Array Data

use Maatify\Common\Pagination\Helpers\PaginationHelper;

$items = range(1, 100);

$result = PaginationHelper::paginate($items, page: 2, perPage: 10);

print_r($result);

Output:

[
    'data' => [11, 12, 13, 14, 15, 16, 17, 18, 19, 20],
    'pagination' => Maatify\Common\DTO\PaginationDTO {
        page: 2,
        perPage: 10,
        total: 100,
        totalPages: 10,
        hasNext: true,
        hasPrev: true
    }
]

---

🔹 Working with PaginationDTO

use Maatify\Common\Pagination\DTO\PaginationDTO;

$pagination = new PaginationDTO(
    page: 1,
    perPage: 25,
    total: 200,
    totalPages: 8,
    hasNext: true,
    hasPrev: false
);

print_r($pagination->toArray());

---

🧩 Helpers

🧱 TapHelper

A lightweight, fluent utility for executing a callback on a given value (usually an object) and returning that same value unchanged —
perfect for cleaner object initialization and inline setup.

---

⚙️ Class

Maatify\Common\Helpers\TapHelper

✅ Features

• Executes a callback on a passed object or value.
• Returns the same value (object, scalar, array, etc.).
• Useful for chaining and fluent API style.
• 100% pure function — no side effects unless your callback modifies the object.

---

🧠 Example Usage

use Maatify\Common\Helpers\TapHelper;
use Maatify\DataAdapters\Adapters\MongoAdapter;

$config = new EnvironmentConfig(__DIR__ . '/../');

$mongo = TapHelper::tap(new MongoAdapter($config), fn($a) => $a->connect());

// $mongo is now a connected adapter
$client = $mongo->getConnection();

---

🧾 Functional Philosophy

TapHelper follows a simple, expressive pattern inspired by functional programming:

Principle	Description
🧩 Isolation	The callback runs in isolation, returning no value.
🔁 Immutability	The original object/value is returned unchanged.
🧼 Clarity	Reduces boilerplate for setup code.
🧠 Testability	Simple to reason about and unit-test (see TapHelperTest).

---

🧪 Unit Test Reference

tests/Helpers/TapHelperTest.php

Covers:

• Returning the same object instance.
• Callback execution correctness.
• Compatibility with scalars and arrays.

vendor/bin/phpunit --filter TapHelperTest

---

🧱 Code Reference

TapHelper::tap(mixed $value, callable $callback): mixed

Executes $callback($value) then returns $value.

---

🧩 Architectural Benefits within the Maatify Ecosystem

Aspect	Benefit
♻️ Fluent Initialization	Enables building adapters and services in one clean line.
🧠 Ecosystem Consistency	Aligns with other helpers like PathHelper, EnumHelper, and TimeHelper.
🧼 Reduced Boilerplate	Replaces multiple setup lines with a single expressive call.
🧩 Universal Reusability	Works seamlessly across all Maatify libraries (bootstrap, data-adapters, rate-limiter, redis-cache, etc.).
