On the [php]architect site today there's a new post about the next edition of their [php]tek conference coming in 2014.
Once again we are planning on hosting our annual php conference: php[tek] in Chicago, IL. You’ll find everything that you love about our conferences again, but also a number of new events and activities that are being planned this year. Check out the website to find more details about the conference this year or lock in your registration early to make sure you will be there. More details will be released over time, and keep an eye out for our Call for Papers that will happen in the coming months.
The 2014 edition of [php]tek will be held in the same place as year's past and will be happening May 19th through the 23rd. There's also several events already planned for next year's event including an open social night, a hackathon and "newcomer sessions" (to introduce people new to [php]tek about activities and the community). You can already pick up your tickets at the Early Bird rates until February 15th, 2014.
