As mentioned on the php|architect blog today, they've extended the Early Bird deadline for the event (in all cities) out to October 4th to ensure that everyone that wants to attend is able to get the discount ($75/ticket).

By popular demand, we have extended the early-bird special for our upcoming CodeWorks tour until Monday, October 4th in order to give everybody an opportunity to sign up for one (or more!) of the tour stops for the low, low, low price of $75 (or even cheaper if you get in with groups of five or more).

They'll be in lots of cities all around the country putting on a one-day event talking about things like building APIs and putting your development tools to work. Check out the event website for more details on the cities they'll be in and how you can get your ticket.
