What's the most easy-to-learn framework?
ErrantX: KohanaPHP hands down.They took codeigniter and pared it down to the bare essentials then rebuilt it from scratch.It's easy to use, has a wealth of libraries (though not too many to confuse the issue) to build stuff with and is extremely fast.As an example of how well it is written I recently built an entire hotel/restaurant booking system (inc. room monitoring & payment gateway) in around 350 lines (not including any HTML).
