This CLASS is designed to take advantage of the USPS API for looking up the corrected (normalized) address for a given physical address. There is very little examples of implementing the USPS API in PHP.
When you instantiate the class, include the API key. See the example.php file for usage. If you don't have a valid USPS.com API, you can get one free at https://www.usps.com/business/web-tools-apis/welcome.htm
