Viite is a single class library for generating and validating finnish reference numbers with check digits according to the [FFI specification](https://www.fkl.fi/en/material/publications/Publications/The_reference_number_and_the_check_digit.pdf).

### Install

[](#install)

Using [Composer](https://getcomposer.org/):

```

### Usage

[](#usage)

Generate a reference number:

```
$input = '123123';
$referenceNumber = Viite\generate($input);

echo $referenceNumber; // "1231234"

// Viite also contains a function for formatting reference numbers according to finnish conventions
echo Viite\format($referenceNumber); // Yields "12312 34"
```

Checking a reference number:

```
if (Viite\check('1231234')) {
    echo 'Yay!';
}
```
