This conference is well-established and I've had a blast most years I've attended! Although their schedule isn't public yet (it will be soon), the other sessions I've heard about on the grapevine sound good. If you want to attend, the date is Friday 26th February and you can buy your tickets on their site. Let me know if I will see you there :)
Earlier in the year I gave a talk at PHP UK in London entitled "Best Practice for API Design". I really enjoyed giving this talk, since I work so much with APIs and enjoy sharing my ideas. The audio is now online so if you missed the talk, feel free to have a listen. You can also see the slides (on slideshare) and also read the series of blog posts I wrote on this topic which originally inspired the talk.
I'm pleased to announce that this year I'll be speaking at PHPUK in London in February. I've attended this conference for the last three years, and attend its related user group, PHP London whenever I can find a reason to be in London on the right day. My talk this time is a brand new one, "Best Practices for Web Service Design", which covers the main points (and pitfalls!) of architecting a web service to be as robust and useful as possible. This is something I've been doing quite a bit of in my day job lately and I'm hoping to pass on some of what I've learned.
