Symfony2 - How to validate an email address in a controller

Question

There is an email validator in symfony that can be used in a form: http://symfony.com/doc/current/reference/constraints/Email.html

My question is: How can I use this validator in my controlelr in order to validate an email address?

This is possible by using the PHP preg_match for usere, but my question is if there is a possibility to use the Symfony already built in email validator.

Thank you in advance.

By using validateValue method of the Validator service

use Symfony\Component\Validator\Constraints\Email as EmailConstraint; // ...  public function customAction() {     $email = 'value_to_validate';     // ...      $emailConstraint = new EmailConstraint();     $emailConstraint->message = 'Your customized error message';      $errors = $this->get('validator')->validateValue(         $email,         $emailConstraint      );      // $errors is then empty if your email address is valid     // it contains validation error message in case your email address is not valid     // ... } // ...
