Simple constraint for Symfony Validator which validates if supplied container number conforms to ISO 6346

Install

Via Composer

composer require ostrolucky/symfony-container-number-validator

Resources

• Container Services International (CSI) container prefix manual
• ISO 6346 wikipedia article

Alternatives

• stormpat/container-validator On top of validation, contains additional functionality and is not coupled to Symfony validator. However, complexity is higher and doesn't contain any tests. I discovered this project only after my library was long done, so don't expect similarities.
• PHP BIC Validation Oldest project, no composer, not PHP warning/notice free, but simple and ready to be used, with GUI integrated.
