PHP and a C++ application

I am doing a project with PHP to a text database. Basically the text database is created in C++. But I only can use exec() function to transfer query commands as an array parameter to its interface, and get result from a temp file. Not like php directly call mysql function, and I want to (if possible) create my function which can do things like mysql function. Anyone know how to do it? Or anyone can tell me which is the best solution to connect a C++ application from PHP?
