Simply import the ProductValidator.class.inc main class file if you are not utilizing auto loaders.

require '/ProductValidator.class.inc';

To use the validator, you can simply call its checkCode($code) method:

$result = ProductValidator\ProductValidator::checkCode('1560213639');

var_dump($result);

checkCode attempts to smartly detect the codes type and returns and array containing the code type, (UPC, EAN, ISBN) the checkDigit for the code, and the isbn pieces if the code is an ISBN.

To validate (TRUE|FALSE) a code you already know the type of, use ProductValidator's individual check functions:

var_dump(ProductValidator\ProductValidator::checkUpc('748196000441');
var_dump(ProductValidator\ProductValidator::checkEan('9781560213635');
var_dump(ProductValidator\ProductValidator::checkIsbn('1560213635');

checkUpc, checkEan and checkIsbn return TRUE if the check digit and code validates, or FALSE if they do not.
