PHP for Embedded Systems?

Question: Can I compile the core PHP engine on a non-POSIX, non-UNIX embedded system? Background: I have a web server running on an embedded microprocessor system for industrial automation. I need a hypertext preprocessor, PHP would be an excellent choice. However, this is not a UNIX-type OS, and I'd like to do without a file system. I do not need all the modules, in principle, a macro preprocessor would do. But I really want to try porting the pure PHP language engine to my machine. Ideally, I would have a call like char* PHP_Evaluate(char*) that evaluates a HTML page with embedded PHP scripts and returns the resulting page. Any pointers on - where to begin looking - how much effort this would be would help a lot.
