PHP / XML API Function antagus.de

I need a function who create a user via xmlapi from antagus.de. Link: [login to view URL] Currently: On my project website, I have a user registration with the following html form fields: firstname (char) name (char) firm (char) street (char) Homenr (int) PLZ (int) city (char) email (char) callnr (int) role (käufer/verkäufer) username (char) password (char) The Response will send the account-information to our mysql database and you can log on my project website. Future: So the user register normaly on my project website with the listed account information above. Now the function of you: If a user register on my project website, the function should trigger a "create user" via xmlapi of [login to view URL] with the SAME account-informations they have type in on the registration on my project website. So the result is, they can login with the SAME account-information on my project website and on the [login to view URL] webinterface. I prefer german speaking guys, but also english speaking guys. Process: 1. You code a example html form like the listed one above. 2. If the user press sumbit, you should program a function via xmlapi [login to view URL] that trigger a "create user" with the typed in account-information 3. The Result is a user in the [login to view URL] database to log in to the webinterface of them. -> I can integrate the function in our project website, if press the "Submit" Button of our current registration system trigger your xmlapi function to create on the same time a user with same account-information in our database and in [login to view URL] database.
