PHP Library to manipulate IBAN and BBAN of countries, with validation, parsing, JSON representation...

Installation

You can install the library with Composer:

composer require elgigi/iban

Usage

Parsing

You can parse an IBAN with Iban::parse() method:

$iban = Iban::parse('FR14 2004 1010 0505 0001 3M02 606');

Or a BBAN with Bban::parse() method:

$bban = Bban::parse('2004 1010 0505 0001 3M02 606', Country::FR);

IBAN and BBAN

Iban object is composed of 2 parts:

• \ElGigi\Iban\Bban object (representation of a BBAN)
• Check digits

Bban object is composed of multiple properties:

• Bank identifier
• Branch identifier ¹
• Account number
• Check digits ¹
• Currency ¹
• Additional digits ¹
• ...

Both object have format() method to have a string representation of object. This method accept a boolean parameter to have the "condensed" representation (without spaces).

JSON

For IBAN, the JSON serialization give the IBAN string representation:

"FR14 2004 1010 0505 0001 3M02 606"

For BBAN, it's little different because, we need the country to build the BBAN object again, so the JSON representation is:

{
  "country": "FR",
  "bban": "2004 1010 0505 0001 3M02 606"
}

After is simple to use parse() methods of classes to build objects again.

Validation

Validation of IBAN

Call Iban::isValid():bool method to known if IBAN is valid.

Or use IbanValidation::validate(): bool static method to valid an IBAN object or string representation.

Also, you can construct an IBAN from BBAN without check digits, library guess them, example:

$iban = new Iban(Bban::parse('2004 1010 0505 0001 3M02 606', Country::FR));
print $iban->format(); // Output: 'FR14 2004 1010 0505 0001 3M02 606'

Validation of BBAN

Depends on banks and countries, BBAN validation is available with method Bban::isValid()

Or uses BbanValidation::validate(): bool static method to valid a BBAN object or string representation.

In case of bank haven't control on BBAN, the method return always TRUE.

Country

An IBAN is associated to a country. A country is represented by Country enum. All countries with IBAN support are listed.

You can also use helpers static methods:

• Country::sepaMembers(): array: list of countries SEPA members
• Country::from(string $iso): Country: country enum value from ISO code

Or methods with country value (FR in example):

• Country::FR->isSepaMember(): bool: country is SEPA member?
• Country::FR->getCurrency(): Currency: main currency of country
• Country::FR->getLanguage(): Language|Language[]: language(s) of country
• Country::FR->getLocale(): string|string[]: locale(s) of country
• Country::FR->getIbanRegex(): string: IBAN regex of country

Language

Language enum is a representation of languages of countries.

To find whose countries speak a language, you can use helper method:

Language::fr->getCountries(): Country[]

Currency

Currency enum is a representation of currency of countries.

To find whose countries have currency, you can use helper method:

Currency::fr->getCountries(): Country[]
