How to integrate Python with PHP?

What a horrible and crazy idea, mixing php and python.  Why would you want to create a mess like that? 
...
Oh, get over yourself.  Yes, I would assume facebook probably uses many different technologies for many different things, though I highly doubt they mix and match them based on which is easier to do mundane thing such as prepending files.  What are you going to do, use python to prepend files, and PHP for everything else? Sorry, but that's a mess (not to mention a horrible idea),  and makes me wonder if you're posting here to amuse yourself by pointing out PHP's (supposed) limitations, or something silly like that.

Thank you, I couldn't have said it better!
