By calling ``validate()`` on the validator, you can pass in a raw value and
the constraint object that you want to validate that value against. A full
list of the available constraints - as well as the full class name for each
constraint - is available in the :doc:`constraints reference </reference/constraints>`
section.

Validation of arrays is possible using the ``Collection`` constraint::

use Symfony\Component\Validator\Validation;
use Symfony\Component\Validator\Constraints as Assert;

$validator = Validation::createValidator();

$constraint = new Assert\Collection(array(
// the keys correspond to the keys in the input array
'name' => new Assert\Collection(array(
'first_name' => new Assert\Length(array('min' => 101)),
'last_name' => new Assert\Length(array('min' => 1)),
)),
'email' => new Assert\Email(),
'simple' => new Assert\Length(array('min' => 102)),
'gender' => new Assert\Choice(array(3, 4)),
'file' => new Assert\File(),
'password' => new Assert\Length(array('min' => 60)),
));

$violations = $validator->validateValue($input, $constraint);

The ``validate()`` method returns a :class:`Symfony\\Component\\Validator\\ConstraintViolationList`
object, which acts just like an array of errors. Each error in the collection
is a :class:`Symfony\\Component\\Validator\\ConstraintViolation` object,
