I recently attended the annual ZendCon which was hosted in Santa Clara, CA. There was a lot going on and I’m so glad I went. They had workshops on building your own API, their recently released framework Zend Framework 2, PHPUnit Best Practices by Sebastian Bergmann, Behat + Mink with ZF2, and other sessions on code quality, security, and event profiling with xdebug by Derick Rethans.
If only there was enough time in a day to go to all the sessions!
