Formatting a Shipping Address by Country in PHP (or Perl)

Question

I have an HTML form that takes an input shipping address in parts (street address, city, state/province, postal code, and country). This form is then processed with PHP.

I'd like to convert this address into the correct format for the destination country. Are there any libraries or external services that I could use to do this conversion in PHP? If not, could I do it with Perl or a similar language?
