Ubuntu Server 12.04 LTS nginx 1.7 PHP 5.4.27

I recently decided to try out Phalcon and followed the installation instructions for Ubuntu from this page https://docs.phalcon.io/en/latest/reference/install.html. During the install I needed to create the dir /etc/php.d, perhaps this was an issue? Anyhow, I followed the instructions and when I tried to restart my webserver (nginx) it would no longer start. I don't get any errors, it just doesn't start. Any ideas on what could of happened during the install to keep nginx from starting?

Any help is appreciated.

Edit nginx now restarts and i feel somewhat foolish :) Configtest on nginx wasn't returning any issues but while looking through some of my other setups I realized that I made a small change quite some time ago that was causing my issue and this was the first time I restarted the server since so it wasn't appearant until now. Completely my mistake and nothing to do with the install :)
