[](#php-luhn---)

An implementation of [Luhn algorithm (aka mod-10 algorithm)](http://en.wikipedia.org/wiki/Luhn_algorithm) to validate (verify the checksum of) credit card numbers in PHP.

\* *This was written to try out PHPUnit, but feel free to use it for anything as long as the MIT License permits*.

To install this library, simply run `composer require` in your project's root directory:

```
$ composer require srph/luhn
```

Usage
-----

[](#usage)

This library is very easy to use! Our `function` **only** accepts one `string` argument and `return`s a `boolean`.
