When applied to an array (or Traversable object), this constraint allows you to apply a collection of constraints to each element of the array.

Applies to property or method
Options
Class Symfony\Component\Validator\Constraints\All
Validator Symfony\Component\Validator\Constraints\AllValidator

Basic Usage

Suppose that you have an array of strings, and you want to validate each entry in that array:

                - NotBlank:  ~
                - Length:
                    min: 5

    // src/Acme/UserBundle/Entity/User.php
namespace Acme\UserBundle\Entity;

use Symfony\Component\Validator\Mapping\ClassMetadata;
use Symfony\Component\Validator\Constraints as Assert;

class User
{
    public static function loadValidatorMetadata(ClassMetadata $metadata)
    {
        $metadata->addPropertyConstraint('favoriteColors', new Assert\All(array(
            'constraints' => array(
                new Assert\NotBlank(),
                new Assert\Length(array('min' => 5)),
            ),
        )));
    }
}

Now, each entry in the favoriteColors array will be validated to not be blank and to be at least 5 characters long.
