So, what you need to have is an HTTP Request from within FoxPro.

http://www.example-code.com/foxpro/http_post_form.asp

gives an example, but it seems to use a third party ActiveX component.

If FoxPro can load any locally resident/installed ActiveX component,
then maybe ...

http://fox.wikis.com/wc.dll?Wiki~ReadUrl

has better examples.


So, using something from that to get the data (XML) and then using
FoxPro's native support for XML and you should be on your way.

But at this stage, I'd be looking to ask for further help in a FoxPro
forum as this is really nothing to do with PHP.

Good luck.

Richard.
