nginx + php-fpm serves php statically

I’m trying to setup nginx and php-fpm on Arch Linux. I’ve been reading through the nginx wiki and its linked guides. Static pages work great. PHP pages don’t seem to get passed to php-fpm. When I view source on my test index.php, I see the actual php source. What am I doing wrong?

I’ve read through some similar questions here, but they’re a bit out of date, using spawn-fcgi, whereas I’m using php-fpm with a linux socket instead of tcp.

You’re using short opening tags which are disabled by default in newer versions of PHP, always, always use full opening tags <?php
