⚙️ Requirements

• PHP ^7.4 || ^8.0

🚀 Installation

Install with Composer:

composer require qdenka/easyvalidation

Autoloading is configured via PSR-4 (QDenka\EasyValidation\).

🛠️ Usage

Factory API

Use ValidatorFactory to retrieve any validator by its type key:

use QDenka\EasyValidation\Application\Validators\ValidatorFactory;

$types = ['email','google_email','disposable_email','url','number','date','ip','uuid','json','base64','phone'];
foreach ($types as $type) {
    $validator = ValidatorFactory::create($type);
    $value = 'test_value_for_' . $type;
    if ($validator && $validator->validate($value)) {
        echo "[$type] valid\n";
    } else {
        echo "[$type] invalid\n";
    }
}

Static Helpers

For quick checks, use the Validator facade:

use QDenka\EasyValidation\Infrastructure\Factories\Validator;

if (Validator::isValidEmail('user@example.com')) {
    echo "Valid email";
}

if (Validator::isGoogleMail('user@gmail.com')) {
    echo "It's a Gmail address";
}

if (Validator::isDisposableEmail('temp@mailinator.com')) {
    echo "Disposable email detected";
}

// Other helpers:
Validator::isValidUrl('https://example.com');
Validator::isValidNumber('123.45');
Validator::isValidDate('2023-04-23');
Validator::isValidIp('2001:db8::1');
Validator::isValidUuid('550e8400-e29b-41d4-a716-446655440000');
Validator::isValidJson('{"foo":1}');
Validator::isValidBase64(base64_encode('hello'));  
Validator::isValidPhone('+1234567890');

📑 Available Validators

⚙️ Configuration

Disposable Domains List

Customize disposable email domains by editing config/disposable_domains.php:

return [
    'mailinator.com',
    '10minutemail.com',
    // add your domains here
];

Ensure all domains are lowercase.

🧩 Extending

To add a new validator:

1. Implement ValidatorInterface in src/Domain/YourType/YourValidator.php.
2. Register your class in ValidatorFactory (src/Application/Validators/ValidatorFactory.php).
3. (Optional) Add a static helper in Validator facade (src/Infrastructure/Factories/Validator.php).
4. Write tests under tests/ following existing patterns.

🧪 Testing

Run PHPUnit:

vendor/bin/phpunit --colors

All tests must pass before merging.
