regex doesnt allow spaces

Question

This bit of regex helps me validate IBAN numbers but it doesnt allow spaces. Some people add spaces to their IBAN numbers, which messes with the validation.

How can i make it so that it allows spaces anywhere the string?

if (preg_match('/^[A-Z]{2}[0-9]{2}[A-Z0-9]{1,30}$/', $iban)) {
  // do something
}

The simple answer to your question is `preg_match('/^[A-Z ]{2}[0-9 ]{2}[A-Z0-9 ]{1,30}$/', $iban)` - insert a space in each character class `[]`. But maybe you should check the question @SilentMonk linked. — SamWhan, Jun 08 '16 at 11:52
@devnull69 "How can i make it so that it allows spaces anywhere the string?" - i.m.o. my sugggestion is the *simple answer* to that question. — SamWhan, Jun 08 '16 at 12:13
The OP certainly meant *additional* spaces, your regex matches spaces in place of characters — devnull69, Jun 08 '16 at 12:22
