🛠️ Helper Utils

Universal collection of PHP 8.5+ helper utilities — dates, strings, arrays, files, network, reflection, hashing, colors, validation and more.

This is a standalone library, not a Symfony bundle. It does not require any framework configuration. Helpers that depend on the current time, timezone, or other side-effects either accept those as explicit method parameters (for static helpers) or are injected via constructor (for service helpers).

🚀 Key Features

• Modern PHP: Strictly typed for PHP 8.5+.
• Zero Configuration: Works out of the box in any project.
• Framework Agnostic: Core logic is pure PHP, with optional integrations for Symfony components.
• Testable: Design focuses on mockability and explicit state management.
• Developer Experience: Consistent naming, clean API, and comprehensive documentation.

📦 Installation

composer require danilovl/helper-utils

🛠️ Included Helpers

Static Helpers

All helper classes are final with private constructors.

Group	Classes	Description
Array	ArrayHelper, ArrayMapHelper, CollectionHelper	Operations with arrays, mapping, filtering, and grouping.
Color	ColorHelper	Color manipulation and conversions (HEX, RGB).
Compare	CompareHelper, VersionHelper	Value and semantic version comparison utilities.
Date	DateHelper, DatePeriodHelper, BusinessDayHelper	Powerful date parsing, manipulation, and period calculations.
File	FileHelper, PathHelper	Filesystem operations, path handling, and metadata.
Form	FormValidationMessageHelper	Symfony Form error extraction and management.
Hash	HashHelper, TokenHelper	Secure hash generation and token utilities.
Json	JsonHelper	Safe JSON encoding and decoding.
Locale	LocaleHelper, CountryHelper	Geographic and linguistic data, country codes.
Network	IpHelper, UrlHelper	IP manipulation (anonymization, ranges) and URL handling.
Number	NumberHelper, MoneyHelper	Formatting numbers, currency, and byte sizes.
Object	CloneHelper, ObjectHelper	Deep cloning and dynamic property access.
Reflection	ReflectionHelper, AttributeHelper, EnumHelper	Advanced reflection for classes, attributes, and Enums.
String	StringHelper, HtmlHelper, TextHelper	String manipulation, slugging, masking, and HTML cleaning.
Validator	ValidatorHelper	Helpers for Symfony validation component.
Misc	RetryHelper	Miscellaneous utilities like retry logic.

Service Helpers

DI-injectable, final readonly where stateless.

• ClockAwareDateHelper: Time-sensitive operations using PSR-20 Clock.
• DoctrineHelper: Doctrine ORM metadata and entity manager shortcuts.
• MemoryHelper: Real-time memory usage tracking and formatting.
• RequestHelper: Convenient wrapper for Symfony's Request objects.
• TimerHelper: Precise code execution timing and measurement.

Enums

• ByteUnit: Constants for data size units (B, KB, MB, etc.).
• ComparisonOperator: Common comparison operators for flexible logic.
• DateFormat: Standardized date and time format strings.

💡 Quick Examples

Static Helpers

use Danilovl\HelperUtils\Helper\Date\DateHelper;
use Danilovl\HelperUtils\Helper\String\StringHelper;
use Danilovl\HelperUtils\Helper\Network\IpHelper;

// Dates — explicit "now" for testability
$age  = DateHelper::calculateAge(new DateTimeImmutable('1990-04-25'));
$past = DateHelper::isPast($someDate, $now);

// Strings
$slug = StringHelper::slugify('Привет, мир!');           // "privet-mir"
$mask = StringHelper::maskEmail('[e-mail]'); // "j******[e-mail]"

// IP Utilities
$ok   = IpHelper::isIpInRange('192.168.1.5', '192.168.1.0/24');
$anon = IpHelper::anonymize('192.168.1.123');             // "192.168.1.0"

Services (Dependency Injection)

use Danilovl\HelperUtils\Service\RequestHelper;
use Danilovl\HelperUtils\Service\ClockAwareDateHelper;

public function __construct(
    private RequestHelper $requestHelper,
    private ClockAwareDateHelper $clock,
) {}

$ip  = $this->requestHelper->getClientIp();
$now = $this->clock->now(); // Easily mockable

🧪 Quality Assurance

We maintain high testing standards to ensure reliability.

composer tests

The package currently includes 397 unit tests and 766 assertions.

Test Coverage

Group	Status
Array, Color, Compare, Date, File, Hash, Json, Locale, Network, Number, Object, Reflection, String, Validator, Misc	✅ Full
Service (Request, Clock, Doctrine, Memory, Timer)	✅ Full

📜 Design Principles

• Immutability: Preference for \DateTimeImmutable.
• Explicitness: "Now"-dependent methods accept an explicit timestamp.
• Safety: Methods follow the doSomething (throws) / trySomething (returns null) pattern.
• Non-Invasive: Wraps powerful libraries (Symfony, Doctrine) rather than reinventing wheels.
• Finality: Classes are final to prevent fragile inheritance.
