Well, rather than asking in the Feedback forum - "Speak directly with the PHP Builder Staff here"; perhaps the General Forum - "Forum for General Help questions pertaining to PHP" would be more appropriate.
However, bubblenut has already pointed out that if the Prolog program could run as a standalone app, PHP can call on it as needed using system functions. (What would be really cool would be if the Prolog runtime libraries came with C API that could be built into a PHP Zend extension.)
