A static class method is called using the :: operator. (see http://www.php.net/manual/en/language.oop5.static.php)

<?php
if(!Validator::isValidAbnOrAcn($abn)) {
  $error = true;
}
?>

All three functions remove all non numeric characters before testing for validity so it is only the numbers in the string that count. I assume that’s what you’re asking? If there are an incorrect number of numbers in the ABN then it’s not valid and the function will return false.

I assume something like:

if (! new Validator($abn))
$error = true;

I guess your code also assumes the number is the correct length.
