PHP 5.3 or 5.5

@BobTheBotMaker do you want to update PHP from 5.3 to 5.4 or greater ahead of deploying wordpress.  @ninjapanzer and I ran into a problem with dereferencing arrays and returning values.  We tracked this problem to the native installation of 5.3 on the Ubuntu 12.04 LTS release.  Do you think we should be testing an updated version of PHP and Ubuntu (LTS 14.X?) ahead of the new website deployment.
