Derafu: Data Processor - Four-Phase Data Processing Library

A PHP library designed to process data through four distinct phases: casting, transformation, sanitization and validation.

What Makes it Different?

Unlike traditional validation libraries that focus solely on validation, Derafu Data Processor offers:

• Clear Phase Separation: Each processing phase (cast → transform → sanitize → validate) has its own purpose and runs in a specific order.
• Independent Transformations: A dedicated transformation layer for complex data conversions, separate from basic type casting.
• Type-Safe Operations: Strong typing and clear error handling in each phase.
• Extensible Rule System: Each type of rule (caster, transformer, sanitizer, validator) follows its own interface.
• Almost Zero Dependencies: just intl extension for specific format rules and Carbon for dates.

Features

• 🎯 Type-Safe Casting: Convert between data types safely.

  • Basic types (string, int, float, bool).
  • Date and time handling.

• 🔄 Data Transformations: Complex data conversions.

  • Base64 encoding/decoding.
  • JSON processing.
  • Slug generation.
  • Character transliteration.

• 🧹 Rich Sanitization Rules: Clean and normalize input data.

  • String sanitization (trim, strip_tags, substring, etc.).
  • Regex-based cleaning (regex_remove, regex_keep).
  • HTML entity handling (htmlspecialchars, htmlentities, etc.).
  • Character set manipulation (remove_non_printable, remove_chars, etc.).

• ✅ Comprehensive Validation: Various validation rules.

  • String validations (required, min_length, max_length, etc.).
  • Number validations (range, gte, lte, etc.).
  • Date validations (after, before, between, etc.).
  • Format validations (email, URL, UUID, etc.).
  • File validations (file, image, mime_types).
  • Array validations (min_items, max_items, not_empty, etc.).

Installation

composer require derafu/data-processor

Basic Usage

use Derafu\DataProcessor\ProcessorFactory;

$processor = ProcessorFactory::create();

// Simple validation.
$result = $processor->process('test@example.com', [
    'validate' => ['email'],
]);

// Multi-phase processing.
$result = $processor->process(' TEST@EXAMPLE.COM ', [
    'transform' => ['lowercase'],
    'sanitize' => ['trim'],
    'validate' => ['email', 'max_length:255'],
]);

// Array validation.
$result = $processor->process([1, 2, 2, 3], [
    'validate' => ['unique', 'max_items:5'],
]);

// File validation.
$result = $processor->process($_FILES['upload'], [
    'validate' => ['file:2M', 'mime_types:application/pdf,image/jpeg']
]);
