BIC Validation Issue

[hofmannsven]

I'm using the BIC validation and it works fine but I noticed that the BIC number DEUTDBBER is validated as valid, even though it seems to be an invalid BIC number:

Can you help?

You're right. The regular expression is actually wrong.

Should be:

$pattern = "/^[A-Za-z]{4} ?[A-Za-z]{2} ?[A-Za-z0-9]{2} ?([A-Za-z0-9]{3})?$/";

It's a shame I didn't noticed this.

Thank you very much for your help and fast response!

Is it possible to also release this patch for the 1.x version of the package? (see issue #30)

Thank you!
