PHP EU VAT Number Validation

SunVatChecker is a simple and fast PHP dynamic EU VAT Number Validation class that validates a business EU VAT Number using the EU VIES system.

To use SunVatChecker class, you need to define the country and vat number parameters you want to verify. If the Country you are sending to is an EU member, the VAT verification step starts, otherwise, a false response is sent to the user. If the sent VAT Number is in the correct format, an inquiry is made from the EU VIES system, and a true or false response is sent to the user depending on the response. If it is in the wrong format or is not a member of the EU, a false response is sent to the user.
