I am trying to call the USPS API that takes in the zip code and returns XML containing the City Name of the given zip code.
Here is the URL they require:
http://production.shippingapis.com/ShippingAPITest.dll?API=CityStateLookup
&XML=<CityStateLookupRequest USERID="xxxxxxx"><ZipCode ID= "0">
<Zip5>90210</Zip5></ZipCode></CityStateLookupRequest>
In my PHP file, when I echo out the above URL, this is what I get:
http://production.shippingapis.com/ShippingAPITest.dll?API=CityStateLookup&XML=90007
All the XML part of the URL is missing. I need to get curl data from the URL.
Anyone know what I could be missing?
