This year, I took up intensive study of PHP. At the beginning of the year, I poured over the Zend PHP 5 Certification Study Guide, Third Edition by Davey Shafik and Ben Ramsey. I even passed the Zend Certified PHP Engineer exam and earned my Zend Certification. I also took up more of a leadership role in my local PHP user group, KCPHPUG, gave a few talks, and have been hosting meetups both at work and at a local café. In the late Spring/early Summer, I began work on a PHP library called OPHP. In April, I attended the Lone Star PHP conference and got to meet and hang out with quite a few luminaries of the community.
I think I can safely say that 2015 has been a year of PHP for me.
