## Development status

This library is ready to use. The Iban validation should be fine, but there is no warranty. **Please use it at your own risk.**

---

## Features

* full country support of IBAN validation based on SWIFT Registry
* customizable violation messages
* simple to use object-oriented api
* high test coverage
* DIC friendly

---

## Installation

To install `jschaedl/iban-validation` via [composer](https://getcomposer.org/) use

```sh
$ composer require jschaedl/iban-validation
```

You can see this library on [Packagist](https://packagist.org/packages/jschaedl/iban-validation).

## Iban Validation

```php
<?php

use Iban\Validation\Validator;
use Iban\Validation\Iban;

$iban = new Iban('DE89 3704 0044 0532 0130 00');
$validator = new Validator();

if (!$validator->validate($iban)) {
    foreach ($validator->getViolations() as $violation) {
        echo $violation;
    }
}
```

You can also customize the violation messages by providing them via configuration. Just create a `Validator` passing a config array as constructor argument.

```php
<?php

use Iban\Validation\Validator;

$validator = new Validator([
    'violation.unsupported_country' => 'The requested country is not supported!',
    'violation.invalid_length' => 'The length of the given Iban is not valid!',
    'violation.invalid_format' => 'The format of the given Iban is not valid!',
    'violation.invalid_checksum' => 'The checksum of the given Iban is not valid!',
]);
```

You can pass `true` to the second argument of the `Validator::validate(string|Iban $iban, bool $throw = false)` in order
to retrieve exceptions thrown on validation errors.

```php
$validator = new Validator();

try {
    $validator->validate(new Iban('DE89 3704 0044 0532 0130 00'), throw: true);
} catch (Exception $exception) {
    // ...
}
```

## Iban Information

```php
<?php

use Iban\Validation\Iban;
use Iban\Validation\CountryInfo;

$iban = new Iban('IBAN DE89 3704 0044 0532 0130 00');
$iban->countryCode(); // 'DE'
$iban->checksum(); // '89'
$iban->bban(); // '370400440532013000'
$iban->bbanBankIdentifier(); // '37040044'
$iban->format(Iban::FORMAT_PRINT); // 'DE89 3704 0044 0532 0130 00'
$iban->format(Iban::FORMAT_ELECTRONIC); // 'DE89370400440532013000'
$iban->format(Iban::FORMAT_ANONYMIZED); // 'XXXXXXXXXXXXXXXXXX3000'

$countryInfo = new CountryInfo('DE');
$countryInfo->getCountryName(); // 'Germany'
$countryInfo->getIbanStructureSwift(); // 'DE2!n8!n10!n'
$countryInfo->getBbanStructureSwift(); // '8!n10!n'
$countryInfo->getIbanRegex(); // '/^DE\d{2}\d{8}\d{10}$/'
$countryInfo->getBbanRegex(); // '/^\d{8}\d{10}$/'
$countryInfo->getIbanLength(); // 22
$countryInfo->getBbanLength(); // 18
$countryInfo->getIbanPrintExample(); // 'DE89 3704 0044 0532 0130 00'
$countryInfo->getIbanElectronicExample(); // 'DE89370400440532013000'

```
