Don't even bother. PHP is slow... You may create a mixture of C++ and PHP but you'll need to do lots of profiling to understand what is slow. And this is mostly... PHP.

• Is Data Base the Bottle Neck of Web Service? (not really... or why wikimedia has so many servers)
• Slashdot article about Facebook (or how many resources PHP wastes)

Just write in C++ in first place. It is as simple as writing in PHP with modern C++ web framework and good knowledge in C++.

Where to start:

• CppCMS - scalable MVC framework oriented for performance.
• Wt - framework that mimics Qt for web (not sure how it scales well).
