I've had the exact same problem, and if you have a database without subqueries... Unless it gets too complicated and slow I will try to preserve keys and compact indices (similar to array_splice, array_merge...). I'm making a new version that uses the API most of the time. It's slower but cleaner. There are a few things that are not clear, but I'll come back to that when I have a new working version. I think that array_pop, array_shift, array_pad and some of the other functions could be faster. They use _phpi_splice which copies a lot of data around. Perhaps I'll look into this later on.
