bcmath as an optional extension for certain validators

For IBAN & BBAN ISO-codes, PHP is required to be compiled with "--enable-bcmath" for arbitrary precision mathematic checks. Usually, you already have bcmath bundled in your PHP version, since many common PHP packages (php-cli, php-fpm, php5-cgi, libapache2-mod-php5, etc.) in stable GNU/Linux distribution releases (such as Debian) are listed as having bcmath built in to them, as an included module.


Via GitHub

$ git clone

Autoloading is PSR-0 friendly.

Via Packagist & Composer

Require the latest version of ronanguilloux/isocodes with Composer

$ composer require ronanguilloux/isocodes


With Symfony Validator

Install Soullivaneuh/IsoCodesValidator to get IsoCodes working as Validator for Symfony and Silex.

With CakePHP 3

Install gourmet/validation to get IsoCodes working with CakePHP 3 as a validator.

With Laravel

Install pixelpeter/laravel5-isocodes-validation to get IsoCodes working with Laravel 5 as a validator.

Supported PHP versions

  • 7.3
  • 7.4

Unit testing

$ phpunit --testdox --coverage-text

Make utilities

For development & contribution purpose only, a Makefile provides various tools to check your code style, quality & test coverage:

Usual tasks:

	To initialize vendors:  make
	To check code quality:	make quality
	To run tests suite:	    make tests
	To fix code style:	    make cs-fix

Other specific tasks:

	To evaluate code coverage:			        make codecoverage
	To run a simple continuous tests server:	make continuous
	To dry-fix code style issues:			    make dry-fix
	To evaluate code quality stats:			    make stats
	To update vendors using Composer:		    make update

Quality assurance report

Isocodes quality plan is mainly based on phpunit: it runs 980+ unit tests, with separated valid & invalid entry sets. Test values are mainly real data or documented examples from standard documentation, and a few handmade values.

The composer.json already includes these Php Quality Assurance Toolchain libraries:

Just run:

$ make stats -i

XML report outputs are then generated in a new ./build folder

Code covering report built using How-to generate such code coverage report using PHPUnit.
