The Pains and Gains of Upgrading PHP

PHPNW User Group, December 2013
Basically: “would everyone please upgrade to a currently-supported version of PHP”. This talk covers the new features and performance improvements in PHP 5.3, PHP 5.4 and PHP 5.5, and gives some approachable advice on how to handle upgrading between them. This talk was delivered to my local user group and they asked some good questions!
