- validate a string against the ISBN-10, ISBN-13 and EAN-13 formats
- convert an ISBN to ISBN-10, ISBN-13, EAN-13 and GTIN-14 formats
- parse an ISBN and extract registration agency, publisher code, publication code, checksum, etc.

composer require biblys/isbn:^2.3.0
Use case: converting an EAN (9782843449499) to an ISBN-13 (978-2-84344-949-9).
<?php
use Biblys\Isbn\Isbn;
try {
$input = "9782843449499";
$isbn13 = Isbn::convertToIsbn13($input);
echo "ISBN-13: $isbn13"; // Prints ISBN-13: 978-2-84344-949-9
} catch(Exception $e) {
echo "An error occured while attempting to format ISBN $input: ".$e->getMessage();
}

try {
$input = "978-2-843-44949-9";
Isbn::validateAsIsbn13($input);
echo "ISBN $input is valid!";
} catch(Exception $e) { // Will throw because third hyphen is misplaced
echo "ISBN $input is invalid: ".$e->getMessage();
