Iban

New in version 2.3: The Iban constraint was introduced in Symfony 2.3.

This constraint is used to ensure that a bank account number has the proper format of an International Bank Account Number (IBAN). IBAN is an internationally agreed means of identifying bank accounts across national borders with a reduced risk of propagating transcription errors.

Applies to property or method
Options
Class Symfony\Component\Validator\Constraints\Iban
Validator Symfony\Component\Validator\Constraints\IbanValidator

Basic Usage

To use the Iban validator, simply apply it to a property on an object that will contain an International Bank Account Number.
