Simple PHP Validator

This is my version of a simple php validator class.

Install

composer require tyurderi/validator

Usage

$v = new Validator\Validator();

$v->addRule('unique_username', function($fields, $value, $params) {
    // logic goes here
    return true;
});

$v->add('username', 'tyurderi', 'required|min:3|max:30|unique_username', array(
    'required'        => 'The username is required.',
    'min'             => 'The username should be at least 3 characters long.',
    'max'             => 'The username should be at most 30 characters long.',
    'unique_username' => 'The username is already in use.'
));

$v->validate();

if ($v->passes())
{
    echo 'Validation was successfully!';
}
else
{
    echo 'Validation failed.', PHP_EOL;
    foreach ($v->errors() as $message)
    {
        echo $message, PHP_EOL;
    }
}
