PHP compilcation from source to " .so " shared library.

Hi. I've project where I need to integrate PHP interpreter with my C++ desktop application , but I don't want to use PHP functionality as a executble ( making another process for it from C++ application ). I'm wondering i there a way of compiling PHP C/C++ code to shared library where I'll be able to edit PHP's main function and call it from my C++ application just including PHP ".so/.dll" compiled shared library into my project. My application is a Linux based. Please let me know if there's a way of doing that. Thanks.
