reBuy EAN / ISBN Library
========================

[](#rebuy-ean--isbn-library)

A PHP library for validating and converting EAN and ISBN identifiers licensed under the [MIT license](LICENSE.md).

Installation
------------

[](#installation)

To use the library you need PHP 7.1 and [Composer](https://getcomposer.org/). Add the following entry to your `composer.json`.

```
composer require rebuy/ean-isbn-library
```

Usage
-----

[](#usage)

The core of the library are identifier objects representing valid EAN-13, EAN-8, or ISBN-10 identifiers. Identifier objects can be created using a parser which validates and normalizes the identifier string.

```
$parser = new Parser();
$identifier = $parser->parse('978-0091956141');

echo $identifier; // will print '9780091956141'
```

Once you have an identifier object, you can convert it into an alternate representation if available.

```
$converter = new Converter();
$conversion = $converter->convert($identifier);
echo $conversion; // will print '0091956145'
```

Both parsers and converters will throw exceptions if the action can’t be performed. Go to [examples](/examples) for complete executable examples and [docs](docs/ApiIndex.md) for a full API reference.
