Embedding PHP 5 in a C application

All, Can anybody give me a pointer on where I might start to learn how to embed Zend2/PHP 5 inside a stand-alone C application? I realize that by asking a question like this it might imply I am not prepared enough to do handle the answer, but ignoring that, is there a document out there? I guess I could start hacking Apache or something, but I was hoping for more of a tutorial/hand-holding article on the basics. Dante
