Believe it or not, this is not a rhetorical question. I've managed to get Kevlin Henney to do an object masterclass presentation at the UK PHP Conference this year (23rd. Feb). Basically he is going to shed light on areas that upcoming OO PHP developers find difficult. Such things as the correct use of interfaces, exceptions, coding styles, agile development and building larger systems. You get the picture. Kevlin has enormous experience in these areas.
So I need your questions .
What problems would you like answered in a lecture. The lecture will be audio and hopefully video recorded. In any case I'll repost any information here.
The most popular questions are guaranteed to get in. The rest is up to Kevlin.
