PhalconValidation is an independent validation component to validate an arbitrary set of data. This component can be used to implement validation rules that does not belong to a model or collection.

The following example shows its basic usage:

use Phalcon\Validation\Validator\PresenceOf,

$validation = new Phalcon\Validation();

$validation->add('name', new PresenceOf(
        'message' => 'The name is required'

$validation->add('email', new PresenceOf(
        'message' => 'The e-mail is required'

$validation->add('email', new Email(
        'message' => 'The e-mail is not valid'

$messages = $validation->validate($_POST);
if (count($messages)) {
        foreach ($messages as $message) {
                echo $message, '<br>;


Phalcon exposes a set of built-in validators for this component:
