Installation

Requirements

PHP 8.4 or higher
Extensions: curl, json, calendar
Composer

Install via Composer

composer require neuron-php/data

Core Features

The Data component provides:

Input Filtering: Secure wrappers for PHP's filter_input functions
Settings Management: Unified configuration from multiple sources (YAML, INI, ENV)
Environment Variables: .env file loading and management
Data Objects: Specialized objects for common data structures
Parsers: CSV, positional, and name parsing utilities
Array Utilities: Advanced array manipulation functions

Input Filtering

Secure, type-safe wrappers for PHP's filter_input functions with a consistent interface.

Available Filters

Cookie - Access $_COOKIE values
Get - Access $_GET values
Post - Access $_POST values
Server - Access $_SERVER values
Session - Access $_SESSION values

Filter Interface

All filters implement the IFilter interface:

interface IFilter
{
    public static function filterScalar($Data): mixed;
    public static function filterArray(array $Data): array|false|null;
}

Usage Examples

use Neuron\Data\Filter\Get;
use Neuron\Data\Filter\Post;
use Neuron\Data\Filter\Cookie;

// Get scalar values
$page = Get::filterScalar('page');        // From $_GET['page']
$username = Post::filterScalar('username'); // From $_POST['username']
$session = Cookie::filterScalar('session_id'); // From $_COOKIE['session_id']

// Get array values
$filters = Get::filterArray('filters');   // From $_GET['filters'][]
$items = Post::filterArray('items');      // From $_POST['items'][]

// With validation
$email = Post::filterScalar('email');
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    // Valid email
}

Settings Management

The SettingManager provides a unified interface for configuration from multiple sources with fallback support.

Supported Sources

YAML - YAML configuration files
INI - Traditional INI files
ENV - Environment variables
Memory - In-memory configuration

Basic Usage

use Neuron\Data\Settings\SettingManager;
use Neuron\Data\Settings\Source\Yaml;
use Neuron\Data\Settings\Source\Env;

// Create primary source (YAML file)
$yamlSource = new Yaml('/path/to/neuron.yaml');
$settings = new SettingManager($yamlSource);

// Add fallback to environment variables
$envFallback = new Env();
$settings->setFallback($envFallback);

// Get settings (checks YAML first, then ENV)
$dbHost = $settings->get('database', 'host');
$apiKey = $settings->get('api', 'key');

// Set values
$settings->set('cache', 'enabled', 'true');

// Get all section names
$sections = $settings->getSectionNames();

// Get all settings in a section
$dbSettings = $settings->getSectionSettingNames('database');

YAML Configuration Example

# neuron.yaml
database:
  host: localhost
  port: 3306
  name: myapp
  username: root
  password: secret

cache:
  enabled: true
  driver: redis
  ttl: 3600

api:
  endpoint: https://api.example.com
  key: your-api-key
  timeout: 30

INI Configuration Example

; config.ini
[database]
host = localhost
port = 3306
name = myapp

[cache]
enabled = true
driver = file
ttl = 3600

Memory Source

use Neuron\Data\Settings\Source\Memory;

$memory = new Memory();
$memory->set('app', 'name', 'My Application');
$memory->set('app', 'version', '1.0.0');

$settings = new SettingManager($memory);

Environment Variables

The Env class provides secure .env file loading and environment variable management using a singleton pattern.

Basic Usage

use Neuron\Data\Env;

// Get singleton instance (auto-loads .env from document root)
$env = Env::getInstance();

// Get environment variables
$dbHost = $env->get('DB_HOST');
$dbPort = $env->get('DB_PORT');
$debug = $env->get('DEBUG');

// Load custom .env file
$env = Env::getInstance('/path/to/custom/.env');

// Set environment variables programmatically
$env->put('RUNTIME_CONFIG=dynamic_value');

// Check if variable exists
if ($env->get('API_KEY')) {
    // API key is set
}

.env File Format

# Database Configuration
DB_HOST=localhost
DB_PORT=3306
DB_NAME=myapp
DB_USER=root
DB_PASSWORD=secret

# Application Settings
APP_ENV=development
APP_DEBUG=true
APP_URL=http://localhost:8000

# API Configuration
API_KEY=your-secret-key-here
API_TIMEOUT=30

# Comments are supported
# DISABLED_SETTING=value

Data Objects

Specialized objects for common data structures with built-in validation and manipulation.

Version

Works with semantic versioning and integrates with the Bump utility.

use Neuron\Data\Objects\Version;

$version = new Version();

// Load from .version.json file
$version->loadFromFile('.version.json');

// Set version components
$version->setMajor(2);
$version->setMinor(1);
$version->setPatch(5);
$version->setPreRelease('beta');
$version->setBuildNumber('123');

// Get formatted version
echo $version->getAsString();  // "2.1.5-beta+123"

// Increment version
$version->incrementPatch();    // 2.1.6
$version->incrementMinor();    // 2.2.0
$version->incrementMajor();    // 3.0.0

// Save to file
$version->saveToFile('.version.json');

DateRange

Manage date ranges with validation and comparison.

use Neuron\Data\Objects\DateRange;

$range = new DateRange(
    new DateTime('2024-01-01'),
    new DateTime('2024-12-31')
);

// Check if date is in range
$date = new DateTime('2024-06-15');
if ($range->contains($date)) {
    // Date is within range
}

// Get duration
$days = $range->getDays();        // Number of days
$months = $range->getMonths();    // Number of months

// Format range
echo $range->format('Y-m-d');     // "2024-01-01 to 2024-12-31"

NumericRange

Handle numeric ranges with validation.

use Neuron\Data\Objects\NumericRange;

$range = new NumericRange(10, 100);

// Check if value is in range
if ($range->contains(50)) {
    // Value is within range
}

// Get range properties
$min = $range->getMin();          // 10
$max = $range->getMax();          // 100
$size = $range->getSize();        // 90

// Validate range
if ($range->isValid()) {
    // Min is less than max
}

GpsPoint

Geographic coordinate handling with distance calculations.

use Neuron\Data\Objects\GpsPoint;

// Create GPS points
$point1 = new GpsPoint(40.7128, -74.0060);  // New York
$point2 = new GpsPoint(51.5074, -0.1278);   // London

// Calculate distance
$distance = $point1->distanceTo($point2);   // Distance in kilometers

// Get coordinates
$lat = $point1->getLatitude();
$lon = $point1->getLongitude();

// Validate coordinates
if ($point1->isValid()) {
    // Coordinates are within valid ranges
}

// Format for display
echo $point1->toString();  // "40.7128, -74.0060"

Parsers

Data parsing utilities for various formats and structures.

CSV Parser

Parse CSV data with custom delimiters and headers.

use Neuron\Data\Parsers\CSV;

$csv = new CSV();

// Parse CSV string
$data = $csv->parse("name,age,city\nJohn,30,NYC\nJane,25,LA");

// Parse with custom delimiter
$csv->setDelimiter(';');
$data = $csv->parse("name;age;city\nJohn;30;NYC");

// Parse without headers
$csv->setHasHeaders(false);
$rows = $csv->parse("John,30,NYC\nJane,25,LA");

// Parse from file
$data = $csv->parseFile('/path/to/data.csv');

Positional Parser

Parse fixed-width positional data.

use Neuron\Data\Parsers\Positional;

$parser = new Positional([
    'name' => [0, 10],   // Position 0-10
    'age' => [10, 3],    // Position 10-13
    'city' => [13, 10]   // Position 13-23
]);

$data = $parser->parse("John Doe  30 New York  ");
// Result: ['name' => 'John Doe', 'age' => '30', 'city' => 'New York']

Name Parsers

Parse names in various formats.

use Neuron\Data\Parsers\FirstMI;
use Neuron\Data\Parsers\LastFirstMI;

// Parse "First MI Last" format
$parser = new FirstMI();
$name = $parser->parse("John A. Smith");
// Result: ['first' => 'John', 'middle' => 'A', 'last' => 'Smith']

// Parse "Last, First MI" format
$parser = new LastFirstMI();
$name = $parser->parse("Smith, John A.");
// Result: ['first' => 'John', 'middle' => 'A', 'last' => 'Smith']

Unit Conversion

Common unit conversion utilities for measurements.

use Neuron\Data\UnitConversion;

// Volume conversions
$ml = UnitConversion::usFlOuncesToMilliliters(16);     // ~473.18 ml
$oz = UnitConversion::millilitersToUsFlOunces(500);    // ~16.91 oz

// Weight conversions
$kg = UnitConversion::poundsToKilograms(150);          // ~68.04 kg
$lbs = UnitConversion::kilogramsToPounds(75);          // ~165.35 lbs

// Temperature conversions (if available)
$celsius = UnitConversion::fahrenheitToCelsius(98.6);   // 37°C
$fahrenheit = UnitConversion::celsiusToFahrenheit(20);  // 68°F

// Distance conversions
$km = UnitConversion::milesToKilometers(100);          // ~160.93 km
$miles = UnitConversion::kilometersToMiles(42.195);    // ~26.22 miles

Best Practices

Configuration Management

// Use fallback chain for flexible configuration
$settings = new SettingManager(new Yaml('neuron.yaml'));
$settings->setFallback(new Env());

// This checks neuron.yaml first, then environment variables
$value = $settings->get('section', 'key');

Input Validation

// Always validate filtered input
$email = Post::filterScalar('email');
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
    throw new InvalidArgumentException('Invalid email');
}

// Use array filtering for multiple values
$ids = Get::filterArray('ids');
if ($ids) {
    $ids = array_map('intval', $ids);
    $ids = array_filter($ids, fn($id) => $id > 0);
}

Environment Configuration

// Use .env for local development
// config/.env.development
DB_HOST=localhost
APP_DEBUG=true

// Use environment variables in production
// Set via server configuration or container
