Adapt PHP script to use cURL

Hello, We have current simple php script which works fine. Part if the script is a webform request. The script takes some data from a simple mysql database and makes a webform request out of that. The webform request is made at a shopping cart encoded by ioncube - so we cannot modify the cart itself. The webform is about 6 lines or so of standard html code. Now we want the webform request to be replaced by a cURL function. The PHP script should execute the webform on the server-side and deliver the result to the browser. The browser itself does not execute the HTML webform code. I suspect the way to do this is using cURL. Other options are fine too if they are done on the server side. But no use of javascript or html redirect code executed by the browser. Anybody interested to do this? thanks
