length should not invalidate bar code.

[proseLA]

i have encountered manufacturers who are using a 2 digit suffix at the end of the 12 digit UPC bar code. the 2 digit suffix indicates a packaging of some sort. you are returning false if the length is not the expected length.

barcode-validator/src/BarcodeValidator.php

Lines 71 to 72 in 6512e3b

	// Check if the string length matches the code's desired length
	if (strlen($code) == $length) {

here is one such code: 84788101273501

upczilla does validate this code as true while your validator automatically returns false.

potential solution:

$strlen = strlen($code);
if ($strlen >= $length) {
  $offset = -1 + $length - $strlen;
  // If the string contains only digits
  if (preg_match('/^[0-9]+$/', $code)) {
	if (BarcodeValidator::calculateEANCheckDigit(substr($code, 0, $offset)) == substr($code, $offset, 1)) {
		return true;
	} else {
		return false;
	}
  } else // The code has invalid characters
