No, it isn't. A true 2-dimensional array is completely orthogonal -- anything you can do row-wise you can automatically also do column-wise, without having to write any special functionality. An array of arrays, by its very nature, doesn't have columns as such, so if you want to work with, e.g. $arr[*][1] you have to have special functions to do so. There are other differences, but in a nutshell that's essentially it. Cheers!
