Some additions to the Validator Symfony Component.

Validate a string value based on these rules:

• Be not null.
• Be not blank.
• Be more than or equal to 3 characters.
• Be less than 63 characters.
• Be in alphanumeric and hyphen.
• Do not start with an hyphen.
• Do not end with an hyphen.

Validate a string value based on The Big Username Blocklist. It won't validate if the value is equal to one of these terms.

Validate that a string matches the correct format for a Google Analytics Tracker ID.

Validate that a value fits in one (or more) SMS message.

Validate that a string matches the basic HTML format for a color (#abc or #abcdef)

<?php

namespace AppBundle\Entity;

use MarcW\Validator\Constraints as Assert;

class User

     * The username is used to attribute a subdomain or a subfolder to the user like:
     * https://username.acme.com or https://acme.com/username
     * @Assert\Subdomain
     * @Assert\Username
     */
    private $username;

    /**

    private $googleAnalytics;

    /**

     *
     * @Assert\SmsMessage(max=2)

}
