Newbie question: interacting with Versant databases

Hi everybody, I am really new to PHP and I am evaluating it to build a Web application that needs to interact with the Versant ODBMS server. More specifically, I need to execute queries (written as C++ functions) on the database and then publish the results on the Web page. I think I could create a set of "executables" that contain the different queries, write the results of the query in a text file and then parse the file using PHP, but I would prefer a more "clever" way of interacting with my database... Can I extend the PHP with my C++ functions? Is there anyone that is using Versant and PHP? Thank you. Regards Sandro
