• 🚀 Zero Dependencies: Pure PHP validation. Lightweight and lightning-fast.
• 📁 JSON Single Source of Truth: Patterns are declared declaratively in standard JSON files shared across multiple languages.

Installation

composer require regexto/validators

Quick Start

1. Basic Validation (PHP)

<?php

require 'vendor/autoload.php';

use RegexTo\Validators\Validator;

// 1. Quick boolean test (substring match)
$isMatched = Validator::test('email', 'Please contact us at [e-mail]'); // true

// 2. Strict full-string validation
$isValid = Validator::validate('email', '[e-mail]'); // true

2. Smart Type Auto-Detection

Pass an unknown string, and the validator will identify matching formats:

<?php

require 'vendor/autoload.php';

use RegexTo\Validators\Validator;

$results = Validator::detect('192.168.0.1');
echo $results[0]['pattern']['slug']; // "ipv4"
